Old Town Market Square
Warsaw's marketplace since the late 13th century — a bronze mermaid, four named rows of burgher houses, and the square the whole Old Town rebuilt itself around.

The Old Town Market Square (Rynek Starego Miasta) is the single most photographed spot in Warsaw, and also the one where the city's whole reconstruction story is easiest to feel. Four rows of tall, narrow, colour-banded burgher houses enclose a rectangular square roughly 90 by 73 metres, with a bronze mermaid standing guard at its centre — the same spot where Warsaw's medieval town hall once stood before it was pulled down in 1817.
Every building around you dates, in stone and mortar, from the postwar reconstruction of 1948–1953. But the square's plan, its proportions, and the individual character of each façade were deliberately recreated from paintings, engravings, and photographs — so what you're looking at is not a guess at what a market square might have looked like, but a documented recreation of this one, down to the roofline. This guide goes deeper than a general Old Town overview: the square's history back to Warsaw's founding, the mermaid legend in full, what each of the four named sides holds, and what actually happens here day to day.
01 · History
A Marketplace Since Warsaw's Founding
The square dates to the very end of the 13th century, laid out at the same time as the city of Warsaw itself and built as the commercial and civic centre of what would become Stare Miasto. Until the close of the 18th century, this was not just the heart of the Old Town — it was the heart of all of Warsaw, the place where guilds met, merchants traded cloth, grain, and spices carried in from distant regions, and public life, including the occasional public execution, played out in full view.
At its centre stood the Old Warsaw Town Hall, built before 1429 and rebuilt more than once over the centuries, most substantially after a fire tore through the square in 1607 forced a wave of rebuilding in the late-Renaissance and Baroque styles that gave the surrounding houses much of their current character. By the early 19th century, though, the Old Town had slipped from being the city's functional centre to one of its poorer, more neglected quarters — and in 1817, the authorities demolished the town hall rather than repair it, leaving the square open at its centre for the first time in roughly four hundred years.
That emptiness lasted until 1855, when the current mermaid statue was installed on the old town hall's former footprint — effectively replacing a seat of civic government with a civic symbol. The square carried on as a genuine, if modest, neighbourhood centre through two more world wars until October 1944, when German forces, in the aftermath of the failed Warsaw Uprising, systematically dynamited what remained of the Old Town, this square included. Photographs from early 1945 show it as an open field of rubble, the mermaid gone and every façade reduced to broken brick.
Reconstruction ran from 1948 to 1953, guided by the same principle that shaped the rest of Stare Miasto: recreate the square's 17th- and 18th-century appearance using the most reliable documentary evidence available, chiefly the meticulous Warsaw cityscapes painted by the Venetian artist Bernardo Bellotto in the 1770s, cross-referenced against surviving photographs, engravings, and measured rubble. The result — inscribed by UNESCO in 1980 as part of the wider Historic Centre of Warsaw listing — is widely regarded as the first attempt anywhere to resurrect an entire historic city core rather than restore isolated buildings.
02 · The Mermaid
The Legend at the Square's Centre
The story goes that a mermaid swam up the Vistula from the Baltic Sea and stopped to rest on the riverbank near what would become Warsaw. She lingered, tangling fishermen's nets and freeing their catch, until the fishermen — first annoyed, then charmed by her singing voice — decided not to trap her after all. A wealthy merchant had less patience: he caught and caged her for profit, and it was the same fishermen who heard her cries and set her free. In gratitude, the mermaid — Syrenka — armed herself with a sword and shield and swore to protect the city and its people ever after, which is why Warsaw's coat of arms shows her not as a passive symbol but as an active defender.
A mermaid figure has appeared in the city's heraldry since at least 1390, though the familiar sword-and-shield version dates specifically from 1622. The bronze statue standing in the square today is the work of sculptor Konstanty Hegel and has occupied the exact spot of the old town hall since 1855 — meaning the mermaid has now guarded the square for longer than the town hall that preceded her stood in the same place. The figure visitors photograph today is a well-maintained cast rather than a fragile original; the historic original is preserved inside the Museum of Warsaw, a few steps away on Dekert's Side. It is one of several mermaid statues around the city — a larger, more famous one also stands on the Vistula boulevards — but this is the one that appears on postcards, and the one every walking tour circles back to.
03 · Four sides
Four Rows, Four 18th-Century Names
Each side of the square is named not for a compass direction alone but after a civic reformer from Warsaw's late-18th-century push for burgher rights — a detail most visitors walk past without knowing.
Dekert's Side (north)
Named for Jan Dekert, an 18th-century mayor of Warsaw and a leading voice for burgher rights. Its eleven fused townhouses now form the Museum of Warsaw — walk through what were once separate front doors and you cross from one merchant's house into the next.
Barss' Side (east)
Named for Franciszek Barss, a lawyer and delegate who represented Warsaw's burghers before the Four-Year Parliament. It holds the Adam Mickiewicz Museum of Literature, honouring Poland's national Romantic poet.
Kołłątaj's Side (west)
Named for Hugo Kołłątaj, a priest, political reformer, and co-author of the Constitution of 3 May 1791. This row keeps the square's density of café terraces and souvenir and amber shops at street level.
Zakrzewski's Side (south)
Named for Ignacy Wyssogota Zakrzewski, Warsaw's first modern mayor. It closes the square nearest the lane down to St. John's Archcathedral and Castle Square, and is usually the most photographed row for its steep, narrow gables.
Look closely at the roofline as you cross the square and you can pick out where individual reconstructed façades change hand-painted colour and ornament — pastel pinks and ochres next to deeper reds and blues, some plain, some carrying painted emblems above the doorways. No two houses were rebuilt identically, which is exactly the point: planners were recreating a row of genuinely different merchant houses, not a uniform stage set.
04 · Today
What the Square Is Actually Like Day to Day
The Museum of Warsaw, occupying all eleven fused townhouses of Dekert's Side, is the square's single biggest draw beyond the mermaid — an unusual building in its own right, since visitors walk between rooms through doorways that never existed when each house stood as a separate merchant's residence. Its collection traces the city's history from its medieval founding through the wartime destruction and reconstruction that produced the square you're standing in.
Outside, the square runs on café culture for most of the year: tables spread across the cobbles from Kołłątaj's and Zakrzewski's Sides in particular, and it is entirely normal to spend an hour over coffee or pierogi simply watching the square go by. Street artists and portrait painters set up easels along the arcaded walkways, amber and souvenir shops line the ground floors, and horse-drawn carriages queue near the mermaid for short loops around the Old Town's lanes. In December the square hosts a Christmas market, and through the warmer months it's a routine stop for walking tours, street musicians, and — on quieter mornings before the tour groups arrive — locals cutting across it on their way somewhere else, a reminder that despite the crowds this is still a functioning piece of the city, not only a museum piece.

Frequently Asked Questions
Is the Old Town Market Square worth visiting if I already saw the rest of Stare Miasto?
Yes — the square is the reason the rest of the walk exists. It's the one spot in the Old Town where the mermaid legend, the reconstruction story, and the daily life of the district (cafés, street artists, the Museum of Warsaw) all sit in one compact space. Even a 20-minute loop around its four sides adds detail that a quick pass-through misses.
How old is the Old Town Market Square, really?
The square itself dates to the late 13th century, when Warsaw was founded — making it, in layout terms, one of the oldest urban spaces in the city. What you see today is a reconstruction completed between 1948 and 1953, rebuilt to its 17th- and 18th-century appearance using paintings, engravings, and photographs after German forces levelled it in 1944.
What is the mermaid statue in the square?
The Warsaw Mermaid, or Syrenka, stands at the centre of the square on the exact spot once occupied by the medieval town hall, torn down in 1817. The current bronze, sword-and-shield figure was sculpted by Konstanty Hegel and has stood there since 1855 — a symbol of Warsaw's coat of arms and of the legend of a mermaid who chose to protect the city after local fishermen freed her from a merchant's net.
What's the difference between the four sides of the square?
The four rows of houses are named after four 18th-century civic reformers rather than by compass point alone: Dekert's Side (north, home to the Museum of Warsaw), Barss' Side (east, the Mickiewicz Museum of Literature), Kołłątaj's Side (west, mostly cafés and shops), and Zakrzewski's Side (south). Each row was rebuilt house by house after 1944, so individual façade colours and gable shapes vary block to block.
What is there to do in the square besides look at buildings?
Outdoor café tables spread across the cobbles for most of the year, street artists and portrait painters set up easels along the arcades, and horse-drawn carriages queue near the mermaid for short rides through the Old Town. The square also hosts seasonal markets and events, including a Christmas market in December.
