National Museum of Natural Sciences
The six million specimens at the National Museum of Natural Sciences range from dinosaurs to Mediterranean flora. Founded by Carlos III in 1771, the original collections were displayed in the Royal Cabinet of Natural History. The exhibits, many dating back to the 18th and 19th centuries, include skeletons of a finback whale, a replica Diplodocus dinosaur, and a garden of petrified tree trunks. The 1880’s Palacio de Exposiciones de las Artes e Industrias, off Paseo de la Castellana, was adapted into the museum by 1910 and also houses a technical university.
