A painter, narrator, collector, dramatist, amateur archaeologist, journalist and key figure of the Modernista movement, Santiago Rusiñol conceived of art as a priesthood and of the artist as the chosen one who, due to an ineluctable calling, is predestined to the sacrifice of living his ideal to the ultimate consequences.
the celebration of the Festes Modernistes (1892–1899), the building of the Cau Ferrat (1893–1894) and the inauguration of the monument to El Greco (1898) made Sitges the Mecca of Modernisme and Rusiñol the high priest of his new movement that aspired to transform society through culture.
The plan was commissioned from the architect Francesc Rogent, who incorporated in the façade the large Gothic windows from Sitges's old castle, recently demolished to make way for the new Town Hall.
The following September he moved his collection of wrought iron there from Barcelona, and on 4 November, in the course of the third Festa Modernista, there was another inauguration which was a much bigger and more splendid affair than the first as the artist timed it to coincide with the arrival of two pictures by El Greco he had bought a few months earlier in Paris.
The list of well-known figures of the time who set foot in the rooms of the Cau includes Joan Maragall, Emilia Pardo Bazán, the Belgian musicians Eugène Ysaÿe and Ernest Chausson, Àngel Guimerà, Benito Pérez Galdós, Víctor Balaguer, Ángel Ganivet, Enrique Granados, Narcís Oller, and Manuel de Falla.
Rusiñol’s decision to leave the Cau to the people of Sitges closed the circle begun that far-off night of 5 January 1892, when the artist said in the Fonda Subur that he wanted to take with him in his pictures a souvenir of what he had seen here.
Including them all is an almost impossible undertaking and something that exceeds the aims of this visitor’s guide, whose purpose is just to give an overall view of the man and bring him within reach of those people entering the Cau Ferrat for the first time and thinking it might be just an ordinary museum.
Thanks to Rusiñol and a small group of antique ironwork collectors (amongst them several of friends of his who shared his obsession), the art of wrought iron was no longer seen as the expression of a lesser creative activity and became a subject for study.
In the course of his life, Santiago Rusiñol put together a considerable collection of ceramics which today is concentrated mainly in two of the rooms on the ground floor of the Cau Ferrat, the Kitchen/Dining-room and the Sala del Brollador.
