The first research began with the creation of the Archaeological Museum of Linares in 1956 at the initiative of Rafael Contreras de la Paz who worked to create the museum and for the state's acquisition of the land on which Cástulo stands. Renowned researchers such as Claude Domergue, Álvaro D'Ors, Gloria Trias, Antonio Arribas, etc. took part in this research. Then, from 1969, José María Blázquez took charge of the operations which continued until 1991.  From then until 2011 the government of Andalusia promoted the excavations, restoration, consolidation and maintenance of Cástulo, and also developed the museum.  A new phase of research at Cástulo was set in motion in 2011 when the "FORVUM MMX" project began under the direction of the Regional Ministry of Culture in co-operation with the Andalusian Institute of Iberian Archaeology at the University of Jaén (UJA), and promoted by Linares Town Council with sponsorship from the Andalusian Ministry of Innovation. Forvm MMX Castulo involves the local communities in the archaeological site and in the cleaning and classification of archaeological pottery. In the archaeological Linares Museum they also organise dissemination and educational activities.
