The anchorage at Calescoves, which lies on the southern coast of Menorca, was partially excavated in 1970s and the 1980s by members of the Complutense University of Madrid, the Museum of Menorca and the Centre for Underwater Research of Menorca. During these tasks a large quantity of materials from the 3rd century BC to the 1st century BC were located, including amphorae fragments and other pottery vessels produced in Ibiza and the South of the Italian Peninsula.
The cove’s seabed still preserves a large quantity of archaeological remains, whose conservation is at risk due to the current intense anchorage activity of vessels in the cove. For this reason, in 2017 the Insular Council of Menorca requested the Friends of the Museum of Menorca association to conduct a systematic underwater survey of the cove’s seabed with the aim of protecting these archaeological materials.
An agreement was signed by the Insular Council and the Government of Catalonia to bring to Menorca the ship “Tetis”, which belongs to the CASC. In 2018 archaeological test pits were carried out at different points of the cove by a team formed by archaeologists from CASC, the Museum of Menorca and the Friends of the Museum of Menorca association.
