Unusual Warsaw: 7 places not shown in guidebooks

Warsaw is often seen along a single route: the Old Town, the Royal Route, Łazienki Park. On a second visit, that list is done in one day.

That's when the places come in that guidebooks usually don't mention and tour groups rarely reach. We've put together seven such spots in Warsaw and nearby: an art installation house a meter and a half wide, a garden on a library roof, a cat cafe, and a fortress linked to Napoleon.

💡 In short:

• Warsaw and its surroundings have seven unusual places you won't find in guidebooks: from an art installation house to a fortress by the river.
• Most spots are free, and they're either in the center or 30-40 km from the city, easy to reach by car.

1. Dom Kereta: the world's narrowest house

The Kereta House was squeezed between two old buildings at Żelazna 74, in the Wola district. It was built in 2012 as an art installation designed by architect Jakub Szczęsny. At its narrowest point it's just over a meter wide, and at its widest it reaches 152 cm (as of 09/2026, source).

Officially the structure is called Ermitaż - Dom Kereta. You can't go inside: the house was conceived as a studio for invited writers and artists. It was named after Israeli writer Etgar Keret, whose parents survived the Holocaust.

• Where: ul. Żelazna 74, Wola district, about an 8-minute walk from Rondo Daszyńskiego metro station (per the map).
• Cost: viewing from outside is free, tourists are not allowed inside.

2. The rooftop garden of the University of Warsaw Library

The garden was laid out right on the roof of the University of Warsaw Library and opened in 2002 (as of 09/2026, official website). The project was created by landscape architect Irena Bajerska. It's free, and it's one of the largest rooftop gardens in Europe.

Take the stairs from the main entrance, and a park with a greenhouse, streams, and a glass floor opens up before you. The garden consists of an upper and a lower part, connected by paths, bridges, and small ponds.

• Getting there: ul. Dobra 56/66, about a 15-minute walk from the Old Town (per the map).
• Cost: admission is free, but the roof is only open during the warm season.
• The catch: from November to March the door to the roof is closed, leaving only the library's inner courtyard.

The view from up here is also part of the experience, and it's worth climbing higher for it. From above you can see the city's rooftops, and in summer students sit on the paths with their laptops.

3. Miau Cafe: a cat cafe in central Warsaw

Miau Cafe has been operating since 2016 (as of 09/2026, cafe website). The money to open it was raised through social media, and it remains one of the calmest corners of the center. The concept is simple: you get a coffee, and cats wander around you.

The cats here are sociable, they come to you on their own and happily sit beside you. The cafe is small, so on weekends it's better to come in the morning while the window seats are still free. Check the exact address and opening hours on the cafe's website in advance.

4. The "dollhouse" at Hoża 70

You can't see this house from the street: it's hidden behind apartment blocks, so you need to enter from the courtyard. The building is pre-war, it survived the war and has kept its old appearance almost unchanged. It used to house a chemical factory that dyed wool, then a women's labor cooperative, and now a law firm operates there.

• Where: ul. Hoża 70, a building in the inner courtyard (per the map).
• Cost: free.
• The catch: the courtyard gate is closed outside working hours, so you can only photograph the house when the firm's staff are on site.

5. A mammoth bone in St. Anne's Church

Next, it's worth heading out to Wilanów, to St. Anne's Church. What's surprising here isn't the find itself, but where it ended up. The remains of a prehistoric animal were discovered during the construction of the church and left in the interior. You've probably never seen decor like that in another church.

• Where: Wilanów, next to the palace and park complex (per the map).
• Cost: entry to the active church is free.
• Who it's for: those who have already been to Wilanów Palace and want to add an unusual stop nearby.

6. Modlin Fortress near Warsaw

The most interesting part begins outside the city limits, if you have at least half a day. Many people know Modlin Airport, but the fortress of the same name by the river stays in the shadows. Its outer ring stretches for dozens of kilometers, making it one of the longest fortresses in Europe. The project is attributed to Napoleon, and the complex was later rebuilt under a Russian tsar.

• Getting there: about 30 km from central Warsaw (per the map), near Modlin Airport; easiest by car or commuter train.
• Cost: walking around the grounds is free, guided tours are paid and run on a schedule (as of 09/2026, fortress website).
• The catch: without booking an official tour you risk being left without a guide, and the self-guided route is shorter.

If you don't want to deal with schedules, find a tour of Warsaw and its surroundings on GetYourGuide.

7. Palace and park in Radziejowice

A bit farther from the capital lies Radziejowice, a historic palace and park ensemble that's easy to find along the S8 highway. The palace is built in a classical style with a touch of neo-Gothic, and around it lies an old park with a pond, a church, and a replica of a mill. The park is open to everyone and free, while the palace interior requires a ticket.

• Getting there: about 40 km from Warsaw along the S8 highway (per the map).
• Cost: palace admission is paid, tickets are bought on site, while the park and surrounding grounds remain free.
• Who it's for: a picnic and a relaxed walk on a day off.

⁉️🤔 Frequently asked questions

How much time do I need for all the spots?

You can't cover everything in one day. See the center separately: Dom Kereta, the rooftop garden, Hoża 70, and the cat cafe are all close together. Modlin Fortress and Radziejowice require a separate trip by car. The church in Wilanów is easy to add to the first day.

Can I see the inside of Dom Kereta?

No, the Kereta House is an art installation and a studio for invited authors, so tourists are not allowed inside. From outside you can see the facade and the narrow silhouette between two buildings. The best place to photograph it is from the opposite side of the street.

Is the library rooftop garden open in winter?

No, the roof is only open during the warm season, and from November to March the door upstairs is closed. Admission is free, you don't pay for the garden or the glass floor. Check the opening hours on the library's official website before your visit.

How do I get to Modlin Fortress without a car?

Commuter trains run from Warsaw toward Modlin, and from there you'll need to walk or take a taxi. It's easier to go by car: the fortress is right next to Modlin Airport. Guided tours run on a schedule, and it's best to book in advance.

Which of these places are free?

You can see Dom Kereta from outside, the rooftop garden, the courtyard at Hoża 70, the church in Wilanów, and the park in Radziejowice for free. You only pay for palace admission and for a fortress tour.

In short: what's worth booking

If you have one free day, go for the rooftop garden, Dom Kereta, and Hoża 70: all three are in the center. If you have a car, add Modlin Fortress and Radziejowice. With kids, you can easily stop by the cat cafe.
