Every weekend, the abertis foundation organises free guided tours of the castle (Saturday and Sunday, from 10:00 to 14:00 hours). To take full advantage of visits, which last approximately 45 minutes, groups comprise 15 individuals. Throughout 2010, Castellet Castle welcomed a total of 5,734 visitors.
The abertis foundation’s interest in recovering and raising awareness of the country's historical and artistic heritage has been translated into a series of prestigious actions, the latest of which is the inauguration of a guest collections section in Castellet Castle’s museum area.
Thus, last October, the ceramics lent by Cerdanyola del Vallès Town Council were replaced by pieces from Peralada Castle; these helped participants on the guided tours to understand the fortress’s past. More specifically, in order to interpret the castle's proto-historical past, a collection of Hellenistic figures from Tanagra, Roman glass and a collection of Iberian artefacts are on show. In the mediaeval section, everyday ceramics from the 11th and 12th centuries are on display, along with various illustrative elements of royal, legal and religious power.
