The art collection includes collections from the 4th-17th centuries until the 20th century. We must emphasize the tables attributed to the Master of Viella (15th century) and the ones of the Master of Balaguer (first quarter of the 14th century).

The contemporary art collection came largely from the art collection of the Balaguer City Hall, in which stands out chiefly the collection of the painter from Balaguer Francesc Borràs.  Among other painters are also represented Viola, Ràfols Casamada, Eduard Alcoy, Rosa Siré, Jaume Minguell, etc., and some artists from Balaguer such as Marcel·lí Bergé, Andreu Saiz, Josep M. Llobet, Antoni Collado, etc.
