Unusual Things to See in Prague: Unique & Unexpected Places

Prague is full of famous sights, but nothing compares to the places that feel a little different. In this article, I’ve put together some unusual and offbeat attractions in Prague. Some of them you can easily combine while exploring the city centre, and some of them are completely free!

Idiom – Book Tower Installation

The Idiom sculpture is one of Prague’s most surprising modern artworks. You will find it inside the Prague Central Library on Mariánské náměstí in the Old Town.

It looks like a tall column made of around 8,000 books. The books form a tower from floor to ceiling. Inside, two mirrors create an illusion of endless space. When you look in, it feels like a tunnel that never ends. The installation is also called the “Column of Knowledge” or the “infinite well.” It was created by Slovak artist Matej Krén and has been here since 1998. It symbolizes the idea that knowledge has no limits.

You can only peek inside through a small opening, but that view is the key moment. Many visitors wait their turn because it is not just a photo spot—it is an experience. The effect can feel a bit dizzying, so take your time when looking in.

Hvězda Summer Palace

The Hvězda Summer Palace (Letohrádek Hvězda) is one of Prague’s most unusual Renaissance buildings. You will find it in the Hvězda Game Reserve (Obora Hvězda) in Prague 6 – Liboc, a large forest park with quiet tree-lined paths.

Emperor Ferdinand I of the Habsburg family founded the park itself as a royal hunting and resting area. At its center stands the summer palace, built in 1555–1556. Its shape of a six-pointed star is unique.

The palace has rich Italian stucco decorations with mythological themes. Inside, there is also an exhibition about its history and the famous Battle of White Mountain (1620), which happened nearby. You can see the model of the battle in the basement. After the battle, the area was destroyed and the forest was heavily cut down. Later, it even served as a gunpowder storage during the time of Emperor Joseph II. In the 19th century, both the park and the palace were restored.

Today, Hvězda is a national cultural monument. It is a peaceful place for walking, history, and nature, with a very unique architectural surprise in the middle of the forest.

The Narrowest Street in Prague

The Narrowest Alley in Prague is a tiny passage in Malá Strana, close to Charles Bridge and the Čertovka canal.

It connects U Lužického semináře Street with the courtyard of a small restaurant by the water. The alley is less than half a meter wide, so only one person can pass at a time. Because of this, there is a traffic light to guide pedestrians.

The alley has a medieval origin. It once served as a fire escape route and a practical access path to the river area. Today, it is one of Prague’s most unusual curiosities.

It became popular thanks to social media, and now many tourists come just to experience this extremely narrow space. It is small, simple, and a bit funny, but very typical for hidden Prague.

The Smallest House in Prague

The Smallest House in Prague is a hidden curiosity in the Old Town. You will find it in Anežská Street, near the Convent of St. Agnes.

The house is only about 2.25 metres wide. It was built in 1853 by architect Josef Liebel. The goal was to fill a narrow gap between buildings, where a small passage once existed. At first, the space was just a small passage. Later, they turned it into rooms. For many years, the building even served as a brothel.

What you see now is mainly the front facade of the original house. Behind it is a living residential part. A small sign marks it as the “Smallest House in Prague,” and many visitors stop here for a quick photo.

Speculum Alchemiae

The Speculum Alchemiae – Alchemy museum is one of the most mysterious places in Prague. You will find it in the Old Town, in Haštalská Street, inside one of the city’s oldest preserved houses.

This building survived the large demolition of the Jewish Quarter in the 19th century, which already makes it very rare. In 2002, there were major floods in Prague. During the reconstruction after the floods, workers discovered hidden medieval cellars and underground rooms beneath the house. These spaces are believed to be linked to the time of Emperor Rudolf II and his interest in alchemy.

The museum today shows a recreated alchemist’s workshop and tells stories about the search for the “elixir of life” and the philosopher’s stone. According to legends, famous figures such as Rabbi Löw and Edward Kelley worked in these spaces. One of the most fascinating parts is the underground. A secret passage leads into old tunnels that, according to legends, reach toward Prague Castle and the Old Town.

John Lennon Wall

You will find the Lennon Wall on Velkopřevorské náměstí, just a few minutes walk from Charles Bridge, on the side of Kampa Island.

It is a constantly changing graffiti wall filled with John Lennon-inspired art, Beatles lyrics, peace messages, and modern street art. It started during the communist era as a symbol of freedom and expression, and it still keeps that spirit today.

It’s easy to combine with a walk around Charles Bridge and Kampa Park. The atmosphere is lively and colorful.

Church of the Most Sacred Heart of the Lord

The Church of the Most Sacred Heart of Our Lord is one of the most striking modern churches in Prague. You will find it on Jiřího z Poděbrad Square (Vinohrady quarter), and it is impossible to miss.

It was built between 1928 and 1932 by famous architect Jože Plečnik, who also worked on Prague Castle. The design is unusual and powerful. The shape was inspired by Noah’s Ark. The brick exterior gives it a strong and modern look, very different from traditional churches. The church tower is one of its biggest highlights. It is 42 metres high and holds the largest clock in the Czech Republic. The clock face is huge and clearly visible from far away. Inside, the church is calm and impressive. You will see a white marble altar and a large golden statue of Christ above it. There are also statues of Czech saints in the interior.

Today, the church is a national cultural monument and even a candidate for the UNESCO list. It is a great stop in Prague for anyone who likes architecture, history, and hidden city landmarks.

Infant Jesus of Prague

The Infant Jesus of Prague is one of the most famous spiritual sites in the city. The small wax-covered statue is over 400 years old and originally came from Spain. You can see it in the beautiful Baroque Church of Our Lady Victorious near Charles Bridge. Many people believe it has miraculous powers and visit it for protection and hope.

The statue shows Jesus as a child. He wears royal robes and a crown. One hand blesses visitors. The other holds a small globe with a cross. It is a calm and powerful symbol for many pilgrims.

The church itself is very beautiful and peaceful. The best bonus is the free museum upstairs. There you can see tiny crowns, robes, and gifts from worshippers. One crown was even blessed by Pope Benedict XVI. Even if you are not religious, the place is worth a visit.

Museum of Miniatures

Hidden near Strahov Monastery, the Museum of Miniatures is one of Prague’s most unusual attractions. You will discover tiny works of art that you can only see through a microscope or magnifying glass.

Imagine a caravan of camels inside the eye of a needle, the Lord’s Prayer written on a single human hair, or the world’s smallest book, listed in the Guinness World Records. There are also miniature paintings of famous artists, a tiny Eiffel Tower, and even a little grasshopper playing the violin.

It is a fun and surprising place that shows incredible patience, skill, and creativity.
