This museum ensemble includes the farmhouse Masia Rocosa, from the 16th century, and the Casa Domènech, built between 1908 and 1910 by Domènech i Montaner, his son Pere Domènech and his son-in-law, Francesc Guàrdia. The whole complex was inaugurated as a museum in the year 1998, after some meticulous restoration works.

Lluís Domènech was born in 1849 in Barcelona, the city where he was to unfold a large part of his architectural, intellectual and political activity. His ties with Canet de Mar are due to his mother, Maria Montaner, who was a daughter of the Casa Forta, and to his wife, Maria Roura, who was born in this town of the Maresme as well. These two factors caused the architect to make long stays in the town, above all in the summer. In his office at the Masia Rocosa, he designed such well-known buildings as the Cafè Restaurant and the International Hotel of the Universal Exposition of 1888, the Palau de la Música Catalana, the Hospital de Sant Pau and the University of Comillas, among others. It should also be noted that he erected diverse buildings in Canet de Mar, aside from his own residence. At Riera (torrent) Sant Domènec may be seen the Athenaeum and Casa Roura, while in the woods of Pedracastell stands the castle Castell de Santa Florentina.

The house-museum is quite interesting because Domènech i Montaner always requested copies of his collaboarators’ works. For this reason one finds, for example, the decoration of Barcelona’s Fonda Espanya in his study, elsewhere the plaster models of the University of Comillas, and curious ceramic pieces throughout the house.

Aside from its architectural aspect, the house-museum also reflects other spheres of interest of Domènech i Montaner, and especially his political and publishing activity. Lluís Domènech i Montaner was one of the driving forces behind political Catalanism and here we find a large part of his correspondence and his studies on Catalan heraldics. In the field of printing, the architect designed and directed works of great magnitude, such as the Enciclopedia General del Arte (General Encyclopaedia of Art).

The Modernista route of Canet de Mar is organised at the house-museum. There are seven guided tours that allow one to become acquainted with the town’s heritage as a whole. This heritage is formed by diverse buildings that range from rural and Late Gothic architecture to the purest Modernisme of Lluís Domènech i Montaner and Josep Puig i Cadafalch. There are also Neo-Gothic buildings such as the sactuary Santuari de la Misericòrdia, designed by Francesc Daniel Molina, or works of agricultural Modernisme such as Vil·la Flora, designed by Eduard Ferrés. Aside from this, Canet de Mar was fortunate enough to become the place of residence of persons who, having grown wealthy in the colonies in the Americas, returned to build majestic houses in the eclectic or Neo-Classical styles. This expansion of art was also tied to the growth of industrial and especially textile activity. In Canet there are two paradigmatic examples: the Jover i Companyia Factory, designed by Pere Domènech i Roura, and the Carbonell Sussagna Factory, by Josep Puig i Cadafalch.

In addition to architectural works, the Modernista routes also look at sculptural elements. Canet de Mar is the site of works by some of the great Catalan sculptors from the end of the 19th century and the beginning of the 20th, such as Pau Gargallo, Eusebi Arnau, Josep Viladomat and Josep Pagès i Serratosa.
