The CRAC ("Collective of Archaeological Investigations of Cerdanyola") is a non-profit organization that was born in 1987 following the archaeological excavations at the Ca n'Oliver settlement. It is formed by history, archeology and art history students and graduates. Their main goal is the investigation, protection and dissemination of the historical heritage of Cerdanyola.
In the field of research, the CRAC has collaborated in the excavation campaigns programmed in the Iberian settlement of Ca n'Oliver since 1987 and in Can Xercavins (1991-2002) and has participated in the research work in the church of Vella de Sant Martí, in the bronze hut of Can Bertran, the settlement of the sports center of the UAB (Autonomous University of Barcelona), etc. Some of its members are the authors of scientific papers in which the results of these works are presented.
At the head of the dissemination, since the opening of the settlement of Ca n'Oliver and the Museum, the CRAC has focused its activity on the revitalization of this historical space. In close collaboration with the technicians of the Museum, it prepares each year the annual program Coneguem la cultura ibèrica al poblat de Ca n’Oliver (“Let's get acquainted with the Iberian culture in the settlement of Ca n'Oliver”) with a series of proposals aimed especially at families. This collaboration is regulated by an agreement with the Town Council of Cerdanyola.
Since 2010, the headquarters of the CRAC is in the Museum of Ca n'Oliver and its bibliographic fund specialized in archeology is part of the library of the Museum. Until 1999 the CRAC published the archaeological journal Limes, which has allowed them to develop an exchange program of scientific publications with more than two hundred institutions in Catalonia, all over Spain and some European Union countries. In the Museum's store you can find the magazine.
