The Ancient Symbols You’ll See All Around Venice

Venice is a city that never stopped talking to itself in symbols. Long before street signs and museum placards, Venetians communicated status, allegiance, victory, and piety through carved stone, embroidered cloth, and repeated ritual gestures — and most of that visual language is still sitting there in plain sight, waiting for someone to explain it. After nearly thirty years walking these streets with visitors, I’ve found that once people learn to read even three or four of these symbols, the entire city changes shape in front of them.
Here’s a guide to the recurring symbols you’ll encounter constantly in Venice, and what they actually mean.

The Winged Lion (In Brief)
You cannot walk more than a few minutes in Venice without encountering the winged lion of St. Mark — on flags, church facades, palace corners, even the airport logo. It represents Venice’s patron saint and, according to legend, fulfills a prophecy an angel delivered to Mark himself: “Pax tibi, Marce, evangelista meus” (“Peace be with you, Mark, my evangelist”), inscribed on the open book the lion typically holds under one paw. A closed book or sword instead of an open book generally signaled wartime rather than peace. I’ve written about the lion’s full history and symbolism in detail elsewhere on the site, so I won’t repeat it here — but it’s the essential starting point for understanding everything else on this list, since so many other Venetian symbols exist in relation to it.

The Corno Ducale: A Crown Shaped Like a Horn
If you spend time in the Doge’s Palace or look closely at Venetian coats of arms, you’ll notice a strange, pointed cap appearing again and again — sometimes on its own, sometimes crowning a family crest. This is the corno ducale, the ceremonial headgear worn by every Doge of Venice from the 14th century onward, and it’s one of the more genuinely bizarre symbols in European political history.
Unlike a conventional crown, the corno was a stiff, horn-shaped bonnet made of gemmed brocade or cloth-of-gold, worn over a fine linen cap, its distinctive rear point echoing the ancient Phrygian cap — itself a classical symbol of liberty. Venetians called it the zoia, meaning “jewel.” It was placed on a newly elected Doge’s head with the words “Accipe coronam ducalem Ducatus Venetiarum” — “Receive the ducal crown of the Dogeship of Venice” — and the Doge wore it in essentially every public appearance where the dignity of the Republic needed representing, removing it only in the presence of the Pope. Every Easter Monday, tradition required the Doge to process to the convent of San Zaccaria, where the nuns presented him with a freshly made cap for the coming year.
You’ll see the corno ducale today crowning the coats of arms of the noble families who produced Doges, carved above doorways and painted in Bellini’s famous portrait of Doge Leonardo Loredan. It remains part of Venice’s official municipal coat of arms even now, centuries after the last Doge abdicated to Napoleon in 1797.

Wellhead Crests: A Family’s Signature on Public Water
Scattered across nearly every campo in Venice are stone wellheads — vere da pozzo — that once served as the city’s primary source of fresh water, collecting rain through an ingenious filtration system beneath the paving. Many of these wellheads are carved with coats of arms: a family crest, sometimes a religious emblem, occasionally a guild symbol, marking which noble family or institution funded the well’s construction.
This matters more than it might sound. Fresh water was scarce and precious in a city surrounded by undrinkable seawater, so donating a well was a significant act of civic generosity — and Venetian families made sure everyone who drew water from it knew exactly whose generosity it was. Walking through a quiet campo and finding a worn coat of arms on a well curb is a small, human reminder that Venice’s grand civic infrastructure was built one wealthy family’s ambition at a time.

Crossed Keys and Papal Symbols
Look above the doors of certain Venetian churches and confraternities and you’ll spot two crossed keys, sometimes topped with a triple-crowned tiara. This is one of Christianity’s oldest visual symbols, representing the keys given to St. Peter, understood as the power to bind and loose granted by Christ — and by extension, papal or ecclesiastical authority. In Venice, where church and state were unusually intertwined and the Republic frequently sparred with Rome over jurisdiction, spotting crossed keys on a building is often a clue about which specific religious order or Roman-affiliated institution controlled it, distinct from buildings under purely Venetian civic authority.

The Marriage of the Sea: A Ring Thrown Into the Water
Not every Venetian symbol is carved in stone — some exist only as ritual gesture, repeated so many times across the centuries that the act itself became a kind of civic emblem. Each year on Ascension Day, the Doge would board the Bucintoro, Venice’s opulent gilded ceremonial barge, and sail out into the lagoon accompanied by the city’s dignitaries. At a designated point near the Lido, he would cast a golden ring into the water and declare, in Latin, a symbolic marriage between Venice and the sea — “Desponsamus te, mare, in signum veri perpetuique dominii” (“We wed thee, sea, as a sign of true and everlasting dominion”).
The ceremony began as a commemoration of Venice’s naval conquest of Dalmatia around the year 1000, but it evolved into something closer to a statement of civic identity: Venice’s entire existence, wealth, and survival depended on the sea, so the Republic formalized that dependence into a marriage. The tradition is still reenacted today every year during the Festa della Sensa, and understanding it changes how you look at the water itself — not just scenery, but the literal partner in Venice’s founding myth.

Why Learning These Symbols Changes Your Trip
Once you can identify even a handful of these — the lion’s open versus closed book, a corno ducale crowning a crest, a wellhead with a family’s coat of arms — Venice stops being a beautiful backdrop and starts reading like a document. Every palazzo, every campo, every quiet church door is making a statement its builders fully intended visitors to understand, even if that understanding got lost somewhere in the last two centuries.
This is exactly the kind of layered reading I try to build into a private walking tour — not just “here’s a pretty building” but “here’s what this building was telling every Venetian who walked past it in 1450.” If that kind of depth appeals to you, take a look at our private tours, or if you’re curious how these symbols connect to the carvings I’ve covered elsewhere on the site — patere, hidden sculptures, and the winged lion in full — those companion pieces are worth a read too. And if you’re planning the trip itself, feel free to get in touch and I’ll help you build a route that actually follows the symbolism rather than just the map.
