The Museum is located on the site of the former Pujol i Bausis factory, which produced architectural ceramics and was a major name in the Catalan Modernist movement. They produced tiles and other items used to decorate buildings and spaces declared World Heritage Sites, including the Hospital de Sant Pau and Park Güell.

The Museum can only be visited on a guided tour, which explains the history of the factory, its technological evolution and the artistic importance of its output.

This is an outstanding complex in terms of its wealth of heritage, with five types of ceramic kilns preserved there. The impressive bottle kilns are a key feature, the only examples of their kind in Spain, and among the few still to remain anywhere in Europe. There is also an uncovered kiln, a metal reflex kiln and six Moorish-type kilns, including two spectacularly unique examples buried at a depth of 9 metres.

200 metres from the “La Rajoleta” Ceramic Museum stands the Can Tinturé Museum, the only such establishment focused specifically on sample tiles. Together, the two museums serve to restore the ceramic-making tradition of Esplugues de Llobregat.
