CosmoCaixa Science Museum is an innovative interactive museum for children of all ages that promotes science and learning through permanent and temporary exhibitions, hands-on activities and presentations. CosmoCaixa permanent exhibitions include the real Amazonian rainforest complete with animals and plants typical to the ecosystem, a geological wall with seven types of real rock formations, an exhibition of the evolution of matter and life of Earth, a planetarium, and a kids'favourite Toca, Toca! (Touch, Touch!) exhibition where everything on display can be handled and investigated from every angle.
The building where CosmoCaixa is housed is itself a beautiful example of Catalan Modern, built between 1904 and 1909 by the architect Josep DomГЁnech i EstapГ . The modern steel-and-glass extension to the museum was added in 2004.
