Eureka! Zientzia Museoa

Eureka! Zientzia Museoa is an interactive science museum in Donostia / San Sebastián, set in the Miramon technology park just a short drive from the city centre.

What is there to see at Eureka! Zientzia Museoa?

Spread across more than 8,000 square metres, the museum groups its collection into eight themed rooms where visitors are expected to touch, press, and physically engage with the exhibits rather than just look at them. Displays translate physics, chemistry, and biology into hands-on experiences, which makes the museum appealing to families with children as well as adults looking for a different kind of educational outing.

Two structures stand out architecturally. A Foucault pendulum hangs inside a fourteen-metre glass tower — a classic, visible demonstration of the Earth's rotation that can be viewed from several floors of the building. A second landmark is the astronomical observatory housed in a thirty-metre tower, which, weather permitting, is used for sky observation sessions.

Does Eureka! have a planetarium?

Yes, the museum runs its own digital planetarium. Shows projected onto the dome take visitors on a 3D journey through the Solar System, with a programme designed to suit both families with young children and visitors with a more serious interest in astronomy. It is one of the highlights worth building extra time into a visit for.

What is the Animalia room?

Animalia is the section of the museum dedicated to live animals, home to around twenty species drawn from different ecosystems — from rainforest snakes and desert lizards to marine fish. The exhibit pairs direct contact with the animals with an explanation of why protecting natural habitats matters, blending wildlife education with a hands-on encounter.

What extra activities does the museum offer?

Beyond the permanent exhibition, Eureka! runs themed workshops, including Matemagia, which combines mathematics with magic tricks, and the Theatre of Electricity, a stage show built around electrical phenomena. On site there is also a restaurant-cafeteria, a picnic area, and parking, which makes it straightforward to plan a full-day outing with the family.

Where is it located and what are the opening hours?

The museum stands at Paseo Mikeletegi 43-45, in the Miramon district of Donostia / San Sebastián. Standard hours run Monday to Friday from 10:00 to 19:00 (until 20:00 in July and August), and weekends and public holidays from 11:00 to 20:00. It is closed on 24, 25 and 31 December and on 1 January, which is worth factoring in when planning a visit around those dates.
