A science museum housed in a 19th-century mock-castle on the hillside of Santa Margarita park, with hands-on exhibits, a planetarium, and a working Foucault pendulum. It forms part of the Museos Científicos Coruñeses alongside the aquarium and natural history museum — a combined ticket covers all three.
The planetarium shows are in Spanish but the exhibits need no translation. It is one of the better science museums in northwestern Spain and particularly good for children.
