Brno Observatory and Planetarium

Brno Observatory and Planetarium sits on top of Kraví hora (Cow Hill), a green park just a short walk from the centre of Brno, and it ranks among the most visited science venues in the Czech Republic. Its striking building, reconstructed in 2010–2011 to a design by architect Martin Rudiš, has become a local landmark thanks to its shimmering, futuristic facade that looks almost like a spaceship resting among the trees. The redesign earned the title "Building of the Year of the Czech Republic" in 2012, and GEO magazine later ranked it among the ten most beautiful buildings in Europe.

How do you get there?

The observatory stands at Kraví hora 522/2 in the Brno-střed district, inside Kraví Hora Park. The simplest route from the city centre is tram line 4 to the Náměstí Míru stop, followed by a short uphill walk of just a few minutes to the park entrance and the building itself. Because it's so close to downtown Brno, it's easy to combine a visit here with other sights in the same afternoon.

What will you see?

Inside, the building is organised into several distinct zones. The Digitarium is a modern projection hall showing audiovisual programs about the universe — one of the larger digital planetariums in the country. The Exploratorium invites visitors to try hands-on experiments and interactive exhibits covering physics and astronomy, while the astronomical observation point lets guests look through telescopes at the night sky when conditions allow. An observation deck on top of the building offers sweeping views over Brno and the surrounding countryside, and it's worth the climb even for visitors who skip the planetarium show. Families with children will also find a science walk, an outdoor educational trail laid out around the grounds.

The site's history goes back to the early 1950s: the first public sky observations took place in the summer of 1953, and the facility was formally opened on 16 October 1954, when both the municipal southern observatory and the university's northern observatory were inaugurated together. Since then it has grown into an institution employing roughly twenty staff members who put on close to 2,000 events a year, ranging from planetarium screenings to workshops and live astronomy talks.

When should you visit?

The observatory operates year-round, and planetarium screenings run regardless of weather, making it a solid choice for a rainy day in Brno. Telescope observations, on the other hand, depend on clear evening skies, so it's worth checking the current schedule before heading over — popular shows often require booking a slot in advance, especially on weekends and during school holidays. Admission typically ranges from about 80 to 150 CZK depending on the program chosen.

Frequently asked questions

Do I need to book tickets in advance? For popular planetarium shows, advance booking is recommended, particularly on weekends and during holiday periods, since the projection hall has a limited number of seats.

Is the observatory suitable for children? Yes — the Exploratorium and the outdoor science walk are designed with younger visitors in mind, and several planetarium programs come in age-appropriate versions for families.

How much time should I plan for a visit? A single planetarium show usually lasts 45 to 60 minutes, but if you also want to explore the Exploratorium and take in the view from the observation deck, budget around one and a half to two hours.

Is the observation deck worth visiting even without a show? Absolutely — the deck at the top of Kraví Hora offers one of the nicer views over Brno, and admission to the deck alone is often cheaper than a full program ticket.
