Madrid Planetarium, opened in 1986 in the Enrique Tierno Galván park (Arganzuela district), is a municipal centre that popularises astronomy. The exhibitions are free to enter; only the domed projection room needs a ticket: €3.60 for adults and €1.65 for ages 2-14 and over 65 (prices seen in October 2026). It is open Tuesday to Sunday, 10:00-13:45 and 17:00-19:45, and closed on Mondays. It is a cheap, useful outing on a rainy or very hot day, easy to combine with a walk in the park and the Arganzuela district; allow about 1h30 for a show and the exhibitions.
Highlights

The building in Tierno Galván park
The planetarium stands out for its concrete and glass architecture and its dome, in the middle of a large public park. In the evening the lit building stands against the sky, which makes it a pleasant late-day walk.
The projection room
Under the dome, the shows tell the story of the sky, planets, stars or the history of astronomy on a large hemispheric screen. The programme changes through the year: some shows are for children, others for adults. Check the language of the show before buying: most are in Spanish.
The free exhibitions
Four exhibition areas with free access present astronomy and space exploration. You can visit them without a show ticket.
Observations and activities
The centre also runs talks, workshops and sky observations, following a calendar published on its official website. Places are often limited.
Hours and prices
Tuesday to Sunday, 10:00-13:45 and 17:00-19:45; closed on Mondays, 1 and 6 January, 1 May and 24, 25 and 31 December. Show: €3.60 (adult), €1.65 (ages 2-14 and over 65); free for under-2s who do not take a seat (prices seen in October 2026).

Tips
Show tickets are limited to the capacity of the room: book ahead for weekends and school holidays, or arrive early. For a day in the south-east of the centre, pair it with the Arganzuela district; for more rainy-day ideas, see what to do in Madrid when it rains and Madrid with children.
