In its time it was one of the main buildings of the exhibition, facing the now-disappeared Palace of Fine Arts. It was at the end of the main street running from the
Arc de Triomf to the
Parc de la Ciutadella. Work began in September 1887, but due to many delays, it was not ready on the day of the inauguration on April 8 and was delayed until August 17. For this reason Domènech i Montaner resigned as the responsible architect. At the end of exhibition, Domenech installed an industrial arts workshop related to architecture, with the possible collaboration of Antoni Maria Gallissà i Soqué. Later it was dedicated to museum purposes as a museum of history, archeology, biology and natural sciences. During the
Spanish Civil War it was closed, after suffering some bombing damage by Francoist aviation. From 1942 to 1945 it was a dining hall for Social Aid, and later returned to its function as the Zoology Museum of Barcelona, in which capacity it served, with some interruptions, from 1920 to 2010, when the collection were dismantled and relocated to the new
Museum of Natural Sciences of Barcelona (in Catalan:
Museu de Ciències Naturals de Barcelona) at the
Forum Building. The building received a major restoration in the 1980s by architects Cristian Cirici, Pep Bonet and Carles Bassó. == Building ==
