Prague Planetarium

Prague Planetarium — the largest planetarium in the Czech Republic — sits in the Holešovice district next to Stromovka park, making it one of the easiest family attractions to pair with a green space visit in a single afternoon outing. The building itself is a classic mid-century structure, and the projection dome inside has been wowing children with the cosmos for decades.

The main draw is the domed projection theater, where shows take audiences on immersive journeys through the night sky, the solar system, and deep space. The experience of lying back in a reclined seat and watching stars wheel overhead is genuinely transporting — the kind of moment that sticks with kids long after they've forgotten which museums they visited. Shows cover topics from basic astronomy and constellation identification to more advanced space exploration content, with different programs suited to different age groups.

Children aged 5 and up are generally ready for the planetarium experience. Very young children may find the darkened environment and reclined seating unsettling, so it's worth considering whether your toddler is likely to be comfortable before booking. Older kids, tweens, and teens who have any interest in science or space will find the projection quality genuinely impressive.

Check the show schedule online before visiting — programs vary throughout the week and some may be in Czech only. English-subtitled or English-language shows are available but schedule-dependent. Booking specific show times in advance is recommended, particularly in school holidays when family groups fill the dome.

The planetarium is located right at the edge of Stromovka park, making a combined visit — park walk in the morning, planetarium show after lunch — one of the better family half-day plans in Prague.
