Bellaterra is a decentralized municipal entity of Cerdanyola del Vallès, in the metropolitan area of Barcelona. It is best known for being the location of the Universitat Autònoma de Barcelona. The urbanisation of the neighbourhood started in 1929 when a pharmacist, Bartomeu, leased land from his father-in-law and built the Bellaterra railway station on the Barcelona–Vallès Line. In the central area of Bellaterra is the Park of El Pedregar de Bellaterra, a garden-museum of some 1.2 hectares.
