Planetárium Praha

Prague Planetarium is one of the largest planetariums in Central Europe, located in the Bubeneč district of Prague 7, right next to Stromovka park and the Výstaviště Praha exhibition grounds.

The venue has been in continuous operation since it opened on November 20, 1960, and remains a major educational and entertainment landmark of the Czech capital more than six decades later. Its defining feature is a massive projection dome measuring 23.5 meters in diameter — one of the largest anywhere in the world — under which sky shows, full-dome films and science programs are presented.

What can you see inside?

The heart of the planetarium is the projection hall beneath the great dome, where visitors watch simulations of the night sky along with shows about the Solar System, distant galaxies and other astronomical phenomena. The facility bridges two eras of technology: traditional optomechanical projectors, which have reproduced the movement of stars with remarkable precision for decades, and modern digital projection systems capable of striking 3D animations and astronomy-themed films. This combination makes the shows appealing both to fans of classic star-gazing presentations and to visitors expecting a more contemporary visual experience.

How do you get to Prague Planetarium?

The planetarium sits in a quiet, green corner of Prague 7, bordering one of the city's largest urban parks, Stromovka, and adjoining the Výstaviště Praha exhibition complex, home to numerous fairs and cultural events throughout the year. Thanks to its location next to the park, a visit here pairs naturally with a walk through Stromovka, especially in warmer months. Bubeneč is well connected to central Prague, making the planetarium an easy stop for both residents and visitors exploring the city.

When is the best time to visit?

The planetarium is a year-round attraction, since its shows run regardless of the weather outside, making it a solid choice on rainy or cold days when exploring the city outdoors is less comfortable. That said, in summer, when neighboring Stromovka draws large numbers of walkers and picnickers, many visitors choose to combine a planetarium show with time spent relaxing in the park. For families with children and school groups alike, it works as a reliable addition to a Prague itinerary at any time of year.

Who is this attraction for?

Prague Planetarium appeals to children and adults alike who have an interest in astronomy and space. Its science programs are presented in an accessible way, so visitors without any specialized background can still enjoy the shows fully. It is also a popular destination for school trips and offers a worthwhile alternative for an afternoon in Prague away from the well-trodden Old Town routes.
