Museu Blau

Time Out says

The Museu Blau ('Blue Museum') started in 2011 in the Parc del Fòrum as part of the Natural Science Museum. All 9,000 square metres of it are spread over two floors. At the main entrance you're welcomed by the skeleton of a whale that beached itself on Catalan shores in 1862. The museum is made up of installations and spaces that include 'Planet Life,' an exhibition that takes you through the history of life and its co-evolution with Earth; the media library; and the Science Nest, where children up to age six can explore and play with natural materials.
