University of Warsaw Library Rooftop Garden
A free, hectare-plus garden on top of a working library, overlooking the Vistula — one of Europe's largest green roofs and one of Warsaw's best under-the-radar views.

Most visitors who climb onto the roof of the University of Warsaw's main library building for the first time have the same reaction: this is on top of a library? Spread across more than a hectare, the garden is one of the largest green roofs in Europe, laid out in two connected levels that step down from a working academic building toward the Vistula, with open views across the river that most tourists never think to look for.
It costs nothing to visit, it's a five-minute walk from the Copernicus Science Centre and the riverside boulevards, and it remains genuinely under-visited relative to how good it is — a quiet, plant-filled counterpoint to the Old Town crowds, in the Powiśle neighbourhood just south of the city centre.
01 · The building
A Library Built to Be Climbed On
The new University of Warsaw Library building — universally shortened to BUW, from its Polish name Biblioteka Uniwersytecka w Warszawie — was the winning design in a 1993 architectural competition by Marek Budzyński and Zbigniew Badowski. Construction finished in December 1999, giving the university a dramatically larger home for its collections at the corner of Dobra and Lipowa streets in Powiśle, close enough to the river that the building's lower floors sit almost at the level of the Vistula escarpment.
Budzyński was known for architecture that folded greenery directly into a building's structure rather than treating it as an afterthought, and BUW is probably his best-known Warsaw execution of that idea: rather than stopping at the roofline, the design continues upward into a landscaped garden, with lattice supports built into the building's north face specifically to carry climbing plants up the walls.
The façade itself is worth a slow look before you head up: large copper panels along Dobra Street carry fragments of classical and religious texts rendered in multiple scripts — Polish, Russian, Greek, Arabic, Hebrew, Sanskrit, and passages of musical notation among them — a deliberate nod to the library's role as a repository of written knowledge across cultures. Inside the grounds sits a further surprise: an authentic Japanese tea pavilion, Chashitsu Kaian, donated to the university in 2004 and built from natural materials by a Japanese craftsman — reportedly the only original traditional Japanese building anywhere in Poland.
02 · The garden
Two Gardens, One Hectare, Four Colours
The garden opened a few years after the building itself, in June 2002, designed by landscape architect Irena Bajerska. It is laid out as two connected sections rather than one continuous space. The Lower Garden, roughly 15,000 square metres, sits at the base and holds ponds, a cascading stream, and granite sculptures by Ryszard Stryjecki, functioning as a public park in its own right even before you reach the roof proper.
From there, stairs and ramps climb to the Upper Garden — the actual rooftop section, about 2,000 square metres — divided into four themed plantings arranged by compass direction and colour: the Golden Garden to the north, the Silver Garden to the east, the Crimson Garden to the south, and the Green Garden to the west. Each uses a different palette of flowering shrubs, grasses, and foliage to carry its colour through the seasons, and the layout is genuinely designed as a garden to walk through and linger in, not just a green roof for the view.
That said, the view is a real part of the draw: from the Upper Garden's edge, you get an open sightline across the Vistula toward Praga on the far bank, with the river, the boulevards below, and Warsaw's skyline all visible at once — one of the more rewarding free vantage points in the city, and one that most visitors walking the Old Town or Royal Route never think to seek out.

Practical Notes
Both levels are free and open to anyone, not just students or library cardholders — you don't need to enter the library building itself to reach the garden, since the entrance is a separate access point on Dobra Street near the Gęsta Street junction. The Lower Garden stays open year-round; the Upper Garden's plantings are seasonal, so it closes over the coldest months and is at its fullest roughly from spring through autumn. Because opening hours shift a little by season and can change year to year, check the library's official site for the current schedule if you're planning a visit around a specific date.
05 · A quick contrast
How It Compares to Warsaw's Other Green Spaces
Warsaw isn't short on parks — Łazienki alone covers 76 hectares — but almost none of them are built on top of an active public building in the middle of the city, and none put you at rooftop height over the river for free. The BUW garden rewards a different kind of visit than a big park walk: it's compact enough to see properly in under an hour, structured enough to feel designed rather than incidental, and quiet enough — even midday on weekdays — that it still feels like a discovery rather than a stop on every tour itinerary.
If you only have time for one green space alongside the Old Town and the Royal Route, this is the one that doubles as a viewpoint, an architecture stop, and a genuine rest break, all within a five-minute walk of the river.
The University of Warsaw itself lists the garden among its own must-see campus sights, and it is easy to see why students treat it as an open-air reading room in warmer months — benches and low walls throughout both levels make it easy to sit with a book for an hour rather than just pass through. Late afternoon, in the couple of hours before sunset, tends to be the most rewarding time to visit: the light angles low across the Vistula, the Upper Garden's colour sections read most vividly, and the crowds thin out as day-trippers head back toward the Old Town.
06 · Questions
Frequently Asked Questions
Is the University of Warsaw Library rooftop garden really free?
Yes — both the Lower and Upper Garden are open to the public at no charge, with no ticket or reservation required. It is one of the few genuinely free, large green spaces this close to the Vistula and central Warsaw.
What's the difference between the Upper and Lower Garden?
The Lower Garden (about 15,000 square metres) sits closer to street level and holds ponds, a cascading water feature, and granite sculptures by Ryszard Stryjecki. A flight of stairs and ramps lead up to the Upper Garden (about 2,000 square metres), the true rooftop section, divided into four colour-themed plantings — Golden, Silver, Crimson, and Green — with the best open views over the Vistula.
When is the best time to visit?
The Lower Garden stays open year-round, but the Upper Garden's more delicate plantings mean it closes over winter and is at its best roughly from spring through autumn, when all four colour sections are in bloom. Exact seasonal hours shift slightly year to year, so check the library's website before a special trip.
Who designed the library and the garden?
The building was designed by architects Marek Budzyński and Zbigniew Badowski, who won the 1993 design competition; it opened in December 1999. The rooftop garden itself opened a few years later, in June 2002, designed by landscape architect Irena Bajerska.
How do I get there?
The library sits in Powiśle at the corner of Dobra and Lipowa streets, with the garden entrance on Dobra Street near the Gęsta Street junction. The closest metro stop is Centrum Nauki Kopernik on the M2 line, a short walk away.
