The Lagoon's Population Curve
Three fates on one (logarithmic) scale: proud Venice, colourful Burano, and Torcello, which has almost vanished.
The Chronicle
Every era unfolds at a tap – filter via the bar above.
before ChristVeneti, Romans and an empty lagoon LagoonPower
Long before a city stood in the water, the Veneti – the ancient people who gave the whole region its name – settled along the edge of the lagoon. Under Roman rule the mainland flourished: Altinum (near today's Altino), Aquileia, Padua and Oderzo were prosperous towns on the Via Annia. The lagoon itself was fishing ground, salt garden and waterway – inhabited only by fishermen on stilt dwellings, as the Roman official Cassiodorus famously described around 537: a people living "like waterfowl" between land and sea, whose entire wealth was salt.
These modest beginnings already carried the seed of later Venice: whoever masters the channels, the tides and the salt, masters the lagoon.

421 / 452–697Flight into the lagoon – Torcello before Venice LagoonPower
The Migration Period shook Italy. When Attila's Huns destroyed Altinum and Aquileia in 452, followed a century later by the Lombards, the mainlanders fled to where no cavalry could follow: the islands of the lagoon. According to legend, Venice was founded on 25 March 421 – but what history can actually grasp first is something else: Torcello, not Rialto, became the first centre. In 639 the cathedral of Santa Maria Assunta was built there; its founding inscription survives to this day – the oldest dated document of the lagoon.
Torcello grew into a veritable town with a bishop's seat, palaces and – so tradition has it – at times up to 20,000 inhabitants. That this very "mother of Venice" now counts barely a dozen residents is one of the great ironies of lagoon history.

697–1000First doges, Rialto and the stolen evangelist PowerCulture
In 697, tradition says, the lagoon islands elected their first doge – formally still subjects of Byzantium, in practice increasingly independent. After repelling a Frankish attack, the seat of government moved in 810 to the sheltered island group of Rialto ("rivus altus", deep channel) – the birth of the city of Venice in the narrower sense.
In 828 came the greatest PR coup of the Middle Ages: Venetian merchants smuggled the relics of St Mark the Evangelist out of Alexandria – hidden under pork, which the Muslim customs officers would not touch. The winged Lion of St Mark became the state emblem, St Mark's Basilica the heart of the city, and Venice henceforth had a patron saint of the first rank. Around the year 1000 Doge Pietro II Orseolo secured the Adriatic – ever since, the doge symbolically "married" the sea each year (Sposalizio del Mare).

1000–1204Rise to sea power – and the coup of 1204 PowerTrade
With the Crusades, Venice became indispensable: whoever wanted to reach the Holy Land needed ships – and nobody built them faster than the Arsenal, the state shipyard founded in 1104, arguably Europe's first "factory". Venice charged for transport and supplies with trading privileges across the whole Levant.
The peak of ruthlessness and business acumen combined: the aged, nearly blind Doge Enrico Dandolo simply redirected the Fourth Crusade in 1204 to the Christian city of Constantinople. The richest city in the world was plundered; Venice secured "a quarter and half a quarter" of the Byzantine Empire – Crete, Euboea, strongholds along every important route. The four bronze horses above the portal of St Mark's are loot from Constantinople to this day.

13th–15th c.The trading empire: what came, what wentup to ~150,000 inhabitants Trade
In the late Middle Ages Venice, with at times 100,000 to 150,000 inhabitants, was one of Europe's largest cities – and by far the richest hub between Orient and Occident. The system was brilliantly simple: everything ran through the Rialto.
What came into the lagoon: spices (pepper, cinnamon, nutmeg, ginger) from India and Southeast Asia via Alexandria and the Levantine ports; silk, cotton, carpets, dyes and gemstones via Constantinople and the Black Sea colonies; grain from Apulia and the Crimea; slaves, wax and furs from the East. Marco Polo, who set off from here for the Silk Road in 1271, was merely the most famous of thousands of Venetian long-distance traders.
What left the lagoon: salt from Venice's own salt pans (the "white gold", a state monopoly), glass from Murano – the furnaces were forcibly moved to the island in 1291, for fire safety and to guard the trade secrets –, fine woollens, silk fabrics, weapons, paper and books. And the spices themselves: Venice bought in the Orient and sold on to all of Europe at a handsome markup.
Where the goods were delivered: across the Alpine passes (Brenner, Septimer) to Augsburg, Nuremberg, Vienna and Prague – German merchants, later including the Fuggers, were required to live and trade in the Fondaco dei Tedeschi, their counting house and warehouse right beside the Rialto Bridge. State galley convoys (mude) sailed on fixed schedules to Bruges, Antwerp, London and Southampton (the "Flanders galleys"), to Aigues-Mortes, Tunis, Beirut and Alexandria. Venice was Europe's logistics network – centuries before containers and hubs.

1500–1571Zenith and turning point1570: c. 175,000 PowerTrade
Around 1500 Venice seemed to stand at its peak: mainland possessions stretching almost to Milan, colonies as far as Cyprus, Titian and Bellini painting, Aldus Manutius printing – at times a third of all Europe's books came from Venetian presses. Yet in that same decade the die was cast against Venice without a single shot fired at the city: in 1498 Vasco da Gama reached India by sea around Africa. The spice trade began to bypass the lagoon via Lisbon and later Amsterdam – the Rialto monopoly started to crumble.
In 1571 Venice, with the Holy League, won a glorious victory over the Ottoman fleet at Lepanto – yet lost Cyprus in the very same war. The victory was celebrated; the strategic position nonetheless worsened step by step: the Mediterranean was no longer the centre of the world.

1575 / 1630The great plague waves−50,000 dead in 1630 CatastropheCulture
Twice the plague tore enormous gaps: in 1575–77 around 50,000 people died – a quarter to a third of the city – and in gratitude for its end the church of Il Redentore rose on the Giudecca. In 1630/31 a second wave carried off nearly 50,000 more; this time the city vowed Santa Maria della Salute at the entrance to the Grand Canal. Both feasts – Redentore in July, Salute on 21 November – are celebrated to this day with pontoon bridges across the canals, and they remain among the few festivals that belong to the Venetians themselves.
In fighting the epidemics, Venice incidentally invented a piece of world history: quarantine (from "quaranta giorni", forty days) on the lazaretto islands of the lagoon – see the Lost Places below.
17th/18th c.–1797Carnival, Casanova – and the end of the Republic PowerCulture
In political and economic decline, Venice became Europe's pleasure capital in the 18th century – in a sense the first tourist destination of the modern age. Carnival lasted for months, ridotti (gaming houses) and opera houses flourished, Canaletto painted vedute as souvenirs for English Grand Tour travellers, Casanova and Goldoni shaped the myth. Even then the city lived more from visitors than from trade – a foretaste of things to come.
On 12 May 1797 the 1,100-year-old Republic ended without a battle: under pressure from Napoleon, the last doge Ludovico Manin abdicated and the Great Council dissolved itself. Napoleon plundered the city (the bronze horses, too, travelled to Paris), closed monasteries and scuole – and in the very same year traded Venice away to Austria in the Treaty of Campo Formio.

1797–1866Austrian rule and the bridge to the mainland PowerTourism
Under Austria, Venice at first grew poor but gained two things that would shape its future: in 1846 the railway bridge linked the island city to the mainland for the first time – the end of complete insularity, the beginning of modern travel. And with the railway came the travellers: Byron, Ruskin, later Wagner (who died in the Palazzo Vendramin in 1883) made Venice the yearning destination of Romanticism.
In 1848/49 the city rose up under Daniele Manin and, as the "Repubblica di San Marco", withstood a months-long siege – in vain. Only in 1866, after the Austro-Prussian War, did Venice join the young Kingdom of Italy by plebiscite.
1870–1945Belle Époque on the Lido, Biennale, Marghera TourismCultureTrade
Three decisions that explain today's Venice: first, from the 1870s the Lido became Europe's most fashionable seaside resort – the Grand Hotel des Bains (1900), the Excelsior (1908) and Thomas Mann's "Death in Venice" (1912) built its legend. Second, in 1895 the city founded the Biennale, the world's oldest art biennial (see the golden section below). Third, from 1917 Porto Marghera grew on the mainland: industrial port, refineries, chemicals – jobs, but also the start of the great resettlement of Venetians to the mainland towns of Mestre and Marghera.
The old city survived both world wars almost untouched; in 1933 the road bridge (Ponte della Libertà) joined the railway bridge.

1945–2000Acqua alta 1966 and the great exodus175,000 → 66,000 LagoonTourism
On 4 November 1966 the water stood 194 cm above normal – the worst flood in the city's history, on the same day as the Arno flood in Florence. The world discovered how vulnerable Venice is; UNESCO and private committees ("Save Venice") began decades of rescue work. The MOSE barrier project was planned from the 1980s onward.
In parallel ran the quieter catastrophe: the population of the historic centre plunged from around 175,000 (1951) to about 66,000 (2001). Flats were damp, expensive and without car access; jobs were in Mestre; and tourism increasingly crowded out ordinary rents. Shops for locals gave way to mask boutiques, schools closed – the city began to empty from within even as it filled up from without.

2000–todayOvertourism, MOSE and the tipping pointtoday: below 49,000 TourismLagoon
Around 30 million visitors a year meet a historic centre with fewer than 49,000 residents – at times more guest beds than resident beds were registered, a symbolic tipping point reached in 2023. The extreme flood of November 2019 (187 cm) accelerated the completion of MOSE: since October 2020 the mobile flood gates have genuinely kept the severe acqua alta events out – a success, though bought with high running costs and open questions about the rising sea level.
In 2021 Italy banned large cruise ships from St Mark's Basin and the Giudecca Canal; in 2024 the entry fee for day visitors launched as a world first – both covered in detail in the outlook below. UNESCO has repeatedly debated placing Venice on the List of World Heritage in Danger.

The Islands of the Lagoon
An archipelago of more than 100 islands – each with its own role in the great Venetian clockwork.
Venice (historic centre)
118 islets, 435 bridges, a fish-shaped plan around the Grand Canal. Political, religious and touristic centre – and the scene of Europe's most dramatic population decline.
Murano
Home of the glass furnaces since 1291 – the master glassmakers enjoyed privileges but were forbidden, on pain of death, to leave the lagoon, so the recipes stayed secret. A world brand to this day, even as cheap imports press the genuine workshops.
Burano
Legend says the famous coloured houses helped fishermen find their way home in the fog. World fame through needle lace (merletto) and the buranelli biscuits. Today the lagoon's number-one photo motif – and at the same time a textbook case of population decline: the young move away, houses become holiday flats.
Torcello
First centre of the lagoon, with a cathedral of 639 and Byzantine mosaics of world rank. Malaria, silting and the pull of Venice depopulated the island almost completely – the most extreme decline in the whole lagoon. Hemingway wrote here at the Locanda Cipriani.
Mazzorbo
Linked to Burano by a wooden bridge. Once gardens and monasteries, today a prime example of transformation: the old families dwindle, replaced by municipal housing, holiday flats and the Venissa estate, which revived the nearly extinct Dorona grape – gentle tourism instead of fishing.
Lido
Twelve kilometres of narrow sand between lagoon and Adriatic – with cars and buses, almost a "normal" town. Once Europe's most fashionable seaside resort, today home of the Film Festival – and of many who can no longer afford the old city. Here too, grand hotels of the founding era stand partly empty.
Giudecca
A long chain of islands facing the old city: Palladio's Redentore church, former shipyards and factories (Molino Stucky, now a Hilton). Long a working-class district, today a mix of genuine everyday life, artists' studios and quiet gentrification.
Sant'Erasmo
Larger than the historic centre itself, yet almost unbuilt: here grow the violet artichokes (castraure) and the vegetables for the Rialto market – agriculture in the middle of the lagoon, as for centuries.
San Michele
Venice's cemetery since Napoleonic times, ringed by cypresses. Here rest Stravinsky, Diaghilev, Ezra Pound and Joseph Brodsky. At All Saints a pontoon bridge traditionally leads across.
Pellestrina & Chioggia
Pellestrina: eleven kilometres of fishing villages behind the mighty 18th-century Murazzi stone dikes. Chioggia at the southern end: "Little Venice" with a real fishing port – one of Italy's largest – and far more everyday life than its big sister.
La Bella Laguna – why this city enchants
For all the figures and worries: Venice is and remains the most beautiful total work of art ever built by humans on water.
Architecture beyond compare
Nowhere else do Byzantine gold mosaics (St Mark's), Venetian Gothic (Doge's Palace, Ca' d'Oro), Renaissance (Palladio's San Giorgio Maggiore) and Baroque (the Salute) stand so close together – all mirrored in the water. Every façade on the Grand Canal tells a merchant's story, every campo is a stage. On Burano the colours glow, on Murano the glass, and on the Lido the Art Nouveau villas of the Belle Époque dream on.
Music & theatre
The Teatro La Fenice – the "phoenix" that rose more splendid from every fire – ranks among the most beautiful opera houses in the world; its New Year's concert is broadcast around the globe. Add Vivaldi concerts in Baroque churches, the Teatro Goldoni, chamber music in palazzi and open-air stages on the campi in summer: Venice makes music every evening of the year.
Food & bacari
Venetian cooking is lagoon cooking: sarde in saor, moleche (soft-shell crabs), risotto al nero di seppia, artichokes from Sant'Erasmo. Best enjoyed in the bacari – tiny wine bars with cicchetti morsels and an "ombra" of wine at the counter. Add fish trattorias on Burano (the risotto di gò is legendary), the Michelin-starred Venissa in its walled vineyard on Mazzorbo, and the morning Rialto fish market as theatre for all the senses.
Out on the canals
The gondola is more than a cliché: eleven metres of craftsmanship, asymmetrically built, made for centuries in the same squeri (boatyards). Prefer it simpler? Vaporetto line 1 down the whole Grand Canal is Europe's cheapest palace tour, and the traghetti (gondola ferries) still cross the canal for small change, as they always have. In the evening, when the day visitors have gone, the small canals belong to the lapping water again.
Active in the lagoon
The lagoon is a 550 km² natural paradise: by kayak or SUP through quiet side canals and out to the barene (salt marshes) full of herons and flamingos; learn voga alla veneta – Venetian stand-up rowing – at one of the many rowing clubs; sail a flat-bottomed bragozzo out to the oyster beds. The highlight is the Vogalonga in spring: thousands of rowing boats, zero engines, the whole lagoon one festival.
Lido, beach & cycling
Twelve kilometres of fine sandy beach with the famous capanne (beach huts), gently shelving and family-friendly – and behind it an island made for the bicycle: from the Art Nouveau villas via Malamocco (the oldest village of the lagoon) down to Pellestrina along the Murazzi dikes, towards the fishing boats. In September the red carpet of the Film Festival turns the Lido into Cannes' more beautiful sister.

The numbers behind the postcard.
2026Population decline and tourist tides Tourism
Venice historic centre: below 49,000 residents – less than a third of the 1951 figure. Statistically, more than 600 visitors a year for every resident. Housing drifts into short-term rental; those who stay are older than average. A counter display in a pharmacy on Campo San Bartolomeo has publicly documented the decline for years.
Burano: shrunk from around 6,000 to about 2,000 residents. By day the crowds push through the coloured lanes; by evening the vaporetti carry the island empty again. The master lacemakers are dying out; young Buranelli find neither affordable houses nor work beyond tourism.
Torcello: the extreme case – from a medieval town to around ten permanent residents, in effect an inhabited open-air museum with a cathedral, two restaurants and plenty of reeds.
Mazzorbo: transformation rather than decline – the old fishing and gardening families give way to social housing, second homes and the gentle wine tourism around Venissa.
Lido: change from grand seaside resort to residential and commuter island; the Film Festival brings back the glamour every September, yet icons like the Hôtel des Bains have waited years for revival.
Mestre/Marghera on the mainland, by contrast, count around 180,000 inhabitants – that is where the "real" Venice of today lives, commuting across the bridge to jobs in hotels, bars and museums.
And yet: those who stay in the evening, when the day visitors have gone, experience a city that can be very much alive – children on the campi, rowers on the canals, crowded bacari. It is precisely these Venetians and their new allies who drive the change described in the outlook below.
Lost Places of the Lagoon
Dozens of islands lie abandoned – monastery, lazaretto, fortress, asylum. The most striking:
Poveglia
An 18th-century plague lazaretto, later a psychiatric hospital until 1968 – abandoned ever since and officially off limits. Crumbling wards, the striking bell tower, rampant vines. Known worldwide as "Italy's creepiest island"; plans for sale and reuse have failed repeatedly, while a citizens' initiative ("Poveglia per tutti") campaigns for public use.
Lazzaretto Vecchio
Here in 1423 Venice established the world's first permanent plague hospital – the very word "lazaretto" comes from this island. Excavations found mass graves with more than 1,500 plague victims. Long left to decay, the island is gradually being developed as a museum and archaeology site.
Lazzaretto Nuovo
From 1468 arriving ships and goods had to wait here for 40 days – quarantine as a Venetian invention of public health. The huge Tezon Grande warehouse with its merchants' graffiti survives; volunteers have saved the island, which can be visited in season.
San Giorgio in Alga
Once an important monastery (a future pope was prior here), then prison, powder magazine and a wartime base – today ruins, a lonely tower and birdsong between Venice and Fusina.
Madonna del Monte & co.
Between Murano and Burano the remains of a monastery and powder magazine crumble into the water – standing for a dozen increasingly nameless islets (San Secondo, Sant'Angelo delle Polveri, old Austrian gun batteries) that the lagoon is slowly taking back.
Sant'Ariano
From 1565 the Republic's ossuary: when the cemeteries were full, the bones were brought here. Behind the enclosure wall lies, quite literally, a hill of bones beneath the brambles – the quietest and most uncanny place in the lagoon, close to Torcello.
Ospedale al Mare (Lido)
A vast 1920s seaside sanatorium right on the Lido beach, with its own theatre (Teatro Marinoni). After closure it was for decades perhaps Europe's largest coastal lost place; renovation and conversion into housing and hotels are now under way – decay is getting a second life here.
Counter-example: Sacca Sessola
The "Isola delle Rose" shows it can be done differently: the abandoned sanatorium became a five-star resort – model and warning at once, for the island is thereby no longer publicly accessible either.
🦁 The Biennale – Venice's Window on the World
Founded in 1895 as the "International Art Exhibition of the City of Venice", the Biennale is the oldest and most important art exhibition in the world. The Giardini hold the historic national pavilions (the German one since 1909); the Arsenale – the Republic's former state shipyard – hosts the curated main exhibition. The Art and Architecture Biennales alternate year by year; alongside them run the annual festivals of film (on the Lido, since 1932 the world's oldest film festival), music, theatre and dance. The Golden Lion is one of the most coveted awards in the worlds of art and film. For the city, the Biennale is the economic and cultural counter-model to day tourism: it brings visitors who stay, return – and extend the season deep into November.
61st Art Biennale "In Minor Keys" – conceived by Koyo Kouoh († May 2025) and realised by her team in her spirit; around 110 participants in the Giardini, the Arsenale and more than 50 venues across the city. Preview: 6–8 May.
83rd Mostra del Cinema on the Lido – red carpet outside the Palazzo del Cinema.
Theatre 7–21 June · Dance 17 July–1 August · Music 10–24 October.
Architecture Biennale – in the familiar alternation, 2027 again brings the world's most important architecture exhibition.

Outlook: the Future Will Be Beautiful
Change must come – and it has long since begun. Venice is reinventing itself: as the first city in the world to dose its success wisely instead of choking on it.
- A clear view of the Doge's Palace. Since August 2021, ships above 25,000 GT may no longer pass through St Mark's Basin and the Giudecca Canal – the ocean giants in front of San Marco belong to the past. The result can be seen and heard: calmer water, cleaner air, a panorama like a Canaletto painting. In the long term a cruise port outside the lagoon is planned.
- An entry fee that benefits the city. Launched in 2024 as a world first, the "contributo di accesso" for day visitors is now permanent: in 2026 it applies on 60 days between 3 April and 26 July (weekends and public holidays, 8:30 am–4 pm) – €5 with advance booking, €10 for latecomers; overnight guests are exempt. The revenue flows into canal maintenance and urban upkeep. The new mayor wants to raise the fee to €30–50, and extending it to the lagoon islands (Murano, Burano, Torcello) is under discussion – the direction is right: those who come contribute to preservation, and those who stay overnight are rewarded.
- The off-season becomes the finest season. July and August in the lagoon are growing oppressively hot – and that is exactly what redistributes the flows: April and May with blossoming gardens and the Vogalonga, golden October with its soft lagoon light, November with the Salute feast and the Biennale finale, Carnival in winter. Venice shows its best side in the "bella stagione" – emptier, milder, more genuine. For hosts this means: the season grows longer rather than more hectic.
- MOSE works. Since October 2020 the mobile flood gates have reliably kept the severe acqua alta events out – St Mark's Square stays dry where the duckboards used to stand. For the rising sea level, thinking is already moving on: from additional coastal defences to raising the lowest-lying quarters. Venice has lived with the water for 1,600 years – it is currently learning the next chapter.
- The city fights for its residents – and finds allies. Limits on new holiday flats, smaller visitor groups (max. 25 people, loudspeakers banned), subsidised housing on Mazzorbo and the Giudecca, young craftsmen in old squeri, new university sites: everywhere initiatives are emerging that carry Venice into the future as a living, inhabited city. Burano and the small islands are the early-warning system – and at the same time the laboratory where gentle tourism (Venissa on Mazzorbo leads the way) and genuine island life come together.
Venice has survived Attila, the plague, Napoleon and the flood of 1966 – it will steer mass tourism into good channels too. The lagoon remains what it has always been: the most beautiful proof that people can live with the water. The future will be beautiful.
