The participation of the main artists, musicians and writers of the 19th century in the activities that the artist Santiago Rusiñol organised at his home-studio in Sitges from 1893 has been turned into a veritable temple of Modernisme.

It was so named Cau (hideout), because they wanted it to be a haven for lovers of poetry, and Ferrat (Iron), because he had a collection of wrought iron that he had collected on his travels around Catalonia. The building is now the Cau Ferrat Museum, one of the main museums of the region of Garraf.

It brings together the collections of ancient and modern art put together by the Catalan artist and writer. Painting, drawing, sculpture, wrought iron, ceramics, glass and furniture form a unique artistic collection, which includes some of the sculptural work of Rusiñol, as well as artists such as Casas, Picasso, El Greco, R. Pichot, Mas i Fondevila, Zuloaga, Regoyos i Degouwe de Nucques, Enric Clarasó, Manolo Hugué and Pau Gargallo, among others.

The Cau Ferrat Museum building was refurbished between 2010 and 2014 in order to strengthen the structure and restore the original historic elements.
