Folimanka in Prague: A Park Under the Bridge, a Bunker Underground, and a City with a Second Layer

Folimanka Park and the Folimanka Bunker in Prague: the history of the Botič valley, the Nuselský Bridge, a Cold War atomic shelter, the New Town walls, and a less obvious Prague beyond the main tourist trail.

Prague has places you know exactly how to photograph.

Charles Bridge at dawn. Hradčany from the other bank of the Vltava. Old Town Square with the Astronomical Clock. Golden Lane before the tour groups arrive. Towers, domes, cobblestones, light, postcard perfection.

And then there is Folimanka.

A place that doesn’t pretend to be a major attraction at first glance. A park in a valley. Some greenery, paths, benches, a playground, a sports hall, the Botič stream, and overhead, the massive Nuselský Bridge, while beneath the ground lies one of Prague’s largest Cold War atomic shelters.

It sounds like three different cities.

And that is precisely why Folimanka is so interesting.

People type into Google: Folimanka, Folimanka Prague, Folimanka Park, Folimanka Bunker, Kryt Folimanka. Sometimes they are looking for a green spot for a walk. Sometimes they are interested in the Cold War shelter. Sometimes they stumble upon it through Dan Brown and his Prague mysteries. Or perhaps they simply see a strange green valley cut by a giant bridge on a map and ask: what exactly is this?

The shortest answer is: a park.

But that would be too simple an answer.

Folimanka is a place where Prague reveals its layers all at once: medieval walls, an ancient stream valley, modern infrastructure, a concrete bridge, a Cold War shelter, and the daily life of residents who come here with a dog, a child, or a coffee.

There are places where Prague tells its story from the façade.

Folimanka tells it from the cross-section.

Where is Folimanka?

Folimanka Park is located in Prague 2, in the valley between Vinohrady, Nusle, and the Karlův area, near the New Town.

This is no longer the strict center in a tourist sense, but it is still very close. You can reach it from the Karlův, Nusle, or Vinohrady neighborhoods. There are tram and bus stops nearby, and the easiest orientation is this: look for the valley under the Nuselský Bridge.

Because the Nuselský Bridge is impossible to miss here.

It passes high over the park, heavily, concretely, as if someone had sliced through the green space with a thick line from the city’s twentieth century. On one side, it can feel overwhelming. On the other, it is hard to imagine Folimanka without it. This contrast is the essence of the place: park and concrete, children and the Cold War, stream and highway, stroll and infrastructure.

Folimanka is not “pretty” in a simple way.

It is real.

The Botič Valley, Before the Concrete Arrived

Before the bridge, the sports hall, and the shelter appeared, there was the valley.

The Botič stream flows through Folimanka—a stream that shaped this part of the city. Today, in central Prague, it is easy to forget that beneath the urban grid of streets, bridges, and tracks lies an older logic of terrain: valleys, slopes, streams, wetter places, steeper inclines, more hidden spots.

Folimanka recalls this older logic.

The Official Encyclopedia of Prague 2 describes Folimanka through several layers: the Botič, which formed the valley; the vanished usedlost (suburban estate) of Folimanka, from which the modern name derives; the walls of the New Town; Karlův, Vinohrady, and Nusle; and the more recent twentieth-century history: the construction of the Nuselský Bridge, the shelter, the sports hall, and the park’s sculptural decoration.

This is essentially a ready-made narrative plan.

First, nature creates the valley.

Then humans cultivate the land, establishing orchards, vineyards, and farms.

Then the city builds walls.

Then neighborhoods grow around them.

Then the twentieth century throws a bridge over the valley.

And buries the fear of atomic war underground.

Where Does the Name Folimanka Come From?

The name Folimanka comes from an old usedlost, a suburban estate or farmstead. In this part of Prague, for centuries, there were vineyards, gardens, orchards, and farms connected to the New Town, Vinohrady, and Nusle.

This is important because today’s park might look like a patch of urban greenery between apartment blocks, streets, and a bridge. But its name remembers the place’s earlier life. It recalls the times when Prague was not yet a compact metropolis, and its outskirts had a semi-rural, garden-like, utilitarian character.

Czech sources remind us that the first mention of this area in vineyard registers dates back to 1353. Later documents also mention an apricot orchard. This is a beautiful detail, because suddenly, beneath the concrete of the Nuselský Bridge and under the military logic of the shelter, a completely different Folimanka appears: one scented with grapevines and fruit.

The city likes to cover things up.

But names sometimes poke through the surface like roots.

The Walls of the New Town

Folimanka lies near one of the most interesting traces of medieval Prague: the old walls of the New Town.

When Charles IV founded the New Town in the fourteenth century, it was not just about a few new streets. It was a massive urban project. Prague was to become a great capital. It needed space, churches, squares, markets, monasteries, roads, and defense.

The walls of the New Town were part of this ambition.

In the Karlův and Folimanka areas, fragments of the old fortifications remain. For a tourist walking through the park for the first time, they might look like a picturesque wall on a slope. But if we know what we are looking at, the perspective suddenly shifts.

Folimanka ceases to be just a place under a bridge.

It becomes the boundary of old Prague.

A place where the medieval city met the valley, the stream, the fields, the roads, and the later neighborhoods. Here, it is easy to see that Prague did not grow only through beautiful façades. It grew through decisions about walls, slopes, gates, routes, and what was to remain inside versus outside.

The Nuselský Bridge, or the City Passing Overhead

Over Folimanka runs the Nuselský Bridge.

In Czech: Nuselský most. For many Prague residents, simply Nuselák.

It is one of Prague’s most distinctive bridges, though completely different from Charles Bridge. It has no saints, Gothic towers, or romantic legends. It has concrete, car traffic, and a metro line running through its structure. It connects the Pankrác area with the city center, carrying traffic over the Nusle valley.

The bridge opened in 1973. It is monumental in scale and has strongly changed the landscape of this part of the city. In Folimanka, it passes over the park at a height of about forty meters, creating one of Prague’s most unusual urban contrasts: below, a stroll, greenery, a playground, a stream; overhead, great infrastructure, cars, the metro, the city’s concrete spine.

The Nuselský Bridge is emotionally complex.

On one hand, it is an impressive feat of engineering. On the other, for years it had a dark reputation in Prague, associated with suicides. The installation of safety barriers only reduced this tragic aspect. Therefore, one cannot speak of the Nuselák solely as a technical structure.

It is a bridge that carries people, metro trains, cars, daily life, and the weight of urban memory.

In Folimanka, this is felt particularly strongly.

Because when you stand beneath it, architecture stops being an abstraction. It is above you. A shadow. A rumble. A line across the sky.

The Park Under the Bridge

And yet, Folimanka is not gloomy.

This is one of the paradoxes of this place.

Under the giant bridge, normal, quiet life goes on. Children run around the playground. People sit on benches. Someone exercises. Someone walks a dog. Someone cuts through between neighborhoods. Someone isn’t thinking about the Cold War, the bridge, the walls, or urban history at all.

And that is good.

A city is not just for understanding. It is also for using.

Folimanka Park has paths, greenery, recreation areas, sports fields, a playground, and space for strolling and resting. A pedestrian and cycle path along the Botič also runs through here, connecting this part of the city with further green areas. The Encyclopedia of Prague 2 notes that the network of park paths is adapted for recreation, including walking, strollers, scooters, and bicycles.

Folimanka shows everyday Prague.

Not the one from the guidebook, but the one where residents truly live.

And perhaps that is exactly why it is worth seeing. Because after a few hours among the most important monuments, it is good to enter a place where Prague stops performing for the tourist and starts being itself.

The Folimanka Sports Hall

The name Folimanka also appears in connection with the sports hall.

The Folimanka Sports Hall was built in 1976 according to the design of architect Jiří Sieglo and is primarily associated with the USK Praha club. It is used for basketball and judo, among other sports.

This is another layer of the place.

Not just a park. Not just a shelter. Not just a bridge. Also sport, training, daily use of the city. In many neighborhoods, such facilities are more important to residents than the most picturesque monument. Because it is to the hall that people go every week, where children train, where matches are held, where the place lives to the rhythm of the local community.

In Folimanka, history is not locked in the past.

It is next to someone who is just heading to practice.

The Folimanka Bunker, or the Cold War Under the Park

The most unusual part of Folimanka is invisible.

Underground lies the Kryt Folimanka, also known as the Folimanka Bunker.

It is a civil defense shelter from the Cold War era. The official website of the shelter states that it is the largest underground structure in the Prague 2 district. It has 1,332 m² of area and could accommodate 1,300 people. It is maintained, lit, heated, and remains functional if needed. Public entry is free and does not require prior reservation during open days.

These are dry numbers.

But numbers in such a place quickly begin to work on the imagination.

1,300 people.

Not tourists. Not spectators. Not concert attendees.

People who would go underground if it became too dangerous on the surface.

The shelter is located about 20 meters underground, with its lowest point descending roughly 25 meters below ground level. An earlier adit from World War II, used as a civilian shelter during air raids, was utilized. After the war, in the context of the Cold War, the site was transformed into a permanent civil defense shelter.

When a person enters the bunker, the Prague above ground disappears.

There are no Hradčany. No Art Nouveau façades. No coffee on Vinohrady. There is concrete, doors, corridors, ventilation systems, emergency exits, survival technology, and a very concrete question: what does a city do when it fears the end of the world?

The Cold War in Czech Concrete

Atomic shelters are strange architecture.

They are not built to be beautiful. They are built to give people a chance when the beauty of the world ceases to matter. They are functional, heavy, underground, technical. They do not invite with a façade. They hide.

The Folimanka Bunker was created at the turn of the 1950s and 1960s, during the Cold War. It was part of the civil defense system. Official descriptions emphasize that it is a permanent, adit-type shelter made of concrete blocks, with protections, emergency exits, technical facilities, and the ability to function in a state of emergency.

Today, you can enter it as a visitor.

This is a historical comfort.

We enter out of curiosity, not fear.

But precisely for that reason, it is worth keeping silence in your head. Because such a place is not just an “attraction.” It is a physical trace of the fear that organized life in Central Europe for decades. It reminds us that the twentieth century was not only an era of metros, apartment blocks, sports halls, and bridges. It was also an era of alarm drills, evacuation plans, propaganda, nuclear tension, and questions no one wanted to say aloud.

Folimanka is a park.

But beneath the park lies anxiety.

Visiting the Folimanka Bunker

The Kryt Folimanka is not open every day like a classic museum.

Public tours usually take place once a month, on Saturdays, from 9:00 AM to 3:00 PM. According to information from the Prague 2 district, entry is free and without prior reservation, and the space is largely accessible to children, seniors, and people with limited mobility.

However, it is always worth checking the current dates on the official shelter website or the Prague 2 district page, as the schedule of open days may change.

Visiting Folimanka is not about admiring luxurious interiors. It is more like passing through the technical heart of fear: corridors, rooms, exits, equipment, information boards, furnishings, and survival plans.

The most interesting thing is that the shelter does not look like a film set.

It looks as if it could still function.

And that is what leaves the biggest impression.

Dan Brown and Folimanka

In recent years, Folimanka has gained additional fame thanks to Dan Brown’s novel “The Treasure” (Czech: Tajemství).

In Brown’s literary world, Prague becomes a city of symbols, science, puzzles, and underground tensions. Folimanka fits this story perfectly: hidden under the park, connected to the Cold War, technical, slightly unsettling, yet completely real.

Prague City Tourism notes that the Folimanka Bunker plays an important role in this Prague novel and that visitor interest has grown alongside its popularity. also offers a route inspired by this atmosphere, linking underground Prague, the Folimanka Bunker, and the bastion area of the New Town.

This is interesting because literature often brings to light places in a city that were previously on the margins.

Charles Bridge does not need Dan Brown. Prague Castle does not either.

But Folimanka? Folimanka likes it when someone suddenly says: look underneath.

The Bastion, Karlův, and the City by the Walls

Folimanka connects well with the Karlův area and the old walls of the New Town.

This is an important part of Prague, often overlooked in initial visits. It is a pity, because this is where you can see Charles IV’s ambitious project, the medieval city boundaries, Baroque bastions, later transformations, and beautiful, less crowded viewpoints.

Nearby is the Bastion u Božích muk, a public space arranged on an old bastion, with a view towards Vyšehrad. From here, you can understand how hills, walls, valleys, and fortifications were arranged around the southern part of the New Town.

This is not Prague from the first promotional brochure.

This is the Prague of topography.

Prague, where you must look not only at façades but also at the slope of the street, the course of the walls, the valley of the stream, the line of the bridge, and the sudden opening of the view.

Why is Folimanka a Good Topic for a Walk?

Because it is not obvious.

And unexpected places often best show how a city truly works.

In Folimanka, you can tell the story of Charles IV’s medieval walls, the old boundary of the New Town, the Botič stream, the garden past of Vinohrady and Nusle, twentieth-century modernization, the Nuselský Bridge, the Cold War, atomic shelters, Dan Brown, everyday park life, and the question of what safety means in a city.

That is a lot for one park.

And that is exactly why Folimanka is great for people who have been to Prague once or twice and want to see something beyond the classic route.

Not instead of Hradčany.

Not instead of Charles Bridge.

Rather, after them.

When we already know the postcard Prague, Folimanka shows its technical, urban, and slightly unsettling cross-section.

As if someone lifted the carpet and said: look, there is history here too.

Is It Worth Visiting Folimanka Park?

Yes, but you need to know why.

If you are looking for a monumental monument, Folimanka might surprise you with its ordinariness. It is a park where residents truly spend time. Not every part of it is “pretty” in a tourist sense. There is a bridge overhead. Surrounding slopes, paths, a hall, daily urban infrastructure.

But if you are interested in a less obvious Prague, Folimanka is a very good choice.

It is a place for those who like to see the city in layers. For people interested in urbanism, the Cold War, bunkers, Dan Brown, the Nuselský Bridge, lesser-known parks, and routes off the main tourist stream.

Folimanka will not be the most beautiful place of your trip.

But it might be one of those that stays in your head the longest.

Because it does not look like a set.

It looks like a real city.

How Much Time Do You Need for Folimanka?

A simple walk through the park takes about 30–45 minutes.

If you want to calmly see the park, approach the Nuselský Bridge, walk towards the walls of the New Town and Karlův, it is worth allocating about one hour.

If you catch an open day of the bunker and want to enter the shelter, reserve more time—about 1.5–2 hours in total, depending on the queue, pace, and how much you want to read along the way.

The best option is to combine Folimanka with the Karlův area, the bastion, and a descent towards the New Town or Vyšehrad.

Then the park stops being a separate point.

It becomes part of a larger map.

How to Get to Folimanka?

You can reach Folimanka from several sides.

From Vinohrady and Nusle, it is easiest to head towards the valley under the Nuselský Bridge. From the New Town, you can descend through the Karlův area and the old walls. There are tram and bus stops nearby, and the most convenient route depends on whether you want to start from the park, the bunker, Karlův, or the bastion.

If you plan to enter the bunker, check the official address and date of the open day in advance. The shelter is located in the area of Pod Karlovem street, under the eastern part of the park.

Comfortable shoes are a good idea.

Folimanka lies in a valley, so approaches can lead along slopes, stairs, or inclined paths.

See Folimanka with a Guide

Folimanka can of course be seen on your own. Just descend into the park, look up at the Nuselský Bridge, find the entrance to the shelter on an open day, and walk the paths between greenery, concrete, and traces of old walls.

But with a guide, it is easier to understand that this is not just a park under a bridge.

It is a place where medieval Prague of Charles IV, the Botič valley, the Cold War, modernist infrastructure, urban daily life, and Dan Brown’s literary imagination meet.

Polish guides from [Satori Cities] show Folimanka and its underground context, among others, during the tour [Underground Prague and the Folimanka Bunker – Following Dan Brown]. This is a walk for those who want to see a less postcard-like Prague: bastions, walls, the shelter, twentieth-century tension, and places where history goes beneath the surface.

Because Prague does not end at the towers.

Sometimes it begins twenty meters underground.
