The archaeological site of Castell was discovered in 1935 by Lluís Barceló i Bou, curator of the Cau Museum on the Costa Brava, who carried out the first excavations between 1935 and 1936, with prior authorization from the owner of the lands. The following excavations were carried out between 1943 and 1949 by the archaeologists Miquel Oliva and Francesc Riuró.
