El Poble Espanyol was constructed for the Barcelona International Exhibition in 1929.The idea was promoted by the Catalan architect Josep Puig and was conceived as a village in what was intended to gather the main characteristics of different locations of Spain. The project was designed by the architects Francesc Folguera and Ramon Reventós, and artists Xavier Nogues and Miquel Utrillo. The museum occupies a total area of 42,000 m² and it reproduces various buildings, places and streets representing various Spanish cities. Although initially, the area was only meant to exist for six months (the length of the International Exhibition), the success allowed the retention so it still exists today. At first the open air museum was called Iberona but the dictatorship of Primo de Rivera renamed it Poble Espanyol.
Today the Poble Espanyol has fifteen representative buildings of the Spanish autonomous regions, serves as an open-air architectural museum as well as a popular craft show, in addition to entertainment such as nightclubs and theaters. There is also a replica in Palma de Mallorca.
