It was established in 1904 and belongs to the Royal Academy of Science and Arts of Barcelona (Catalan: Reial Acadèmia de Ciències i Arts de Barcelona). Its main activity is the study of asteroids and comets. It is the fourth most ancient observatory in the world that is still functioning.
The double refractor was built by Mailhat, Paris, in 1904. The visual instrument (the lower of the two tubes) has an aperture of 38 cm and a focal length of 6 meters (f/15.8). The photographic instrument also has an aperture of 38 cm, but a shorter focal length of 4 meters (f/10.5).
