In 2025, systematic underwater archaeological research on the historic wreck of the 'Mentor' resumed under the direction of Dr. Dimitrios Kourkoumelis-Rodostamos, deputy head of the Underwater Antiquities Service. The 'Mentor' sank in September 1802 off the coast of Avlemonas in southeastern Kythera and was one of Lord Elgin's private ships used for transporting antiquities, including parts of the sculptural architectural decoration from the Acropolis monuments. During this year's excavation period, researchers explored areas west and north of the visible wreck of the ship.

An excavation trench, conventionally named Trench 1/2025, was established about five meters to the west of the remaining hull of the ship. The purpose of this trench was to investigate whether any remnants of the ship's hull had been preserved in that area. However, during the excavation, no traces of the ship were found, indicating the possible erosion or removal of the wreck over time. The ongoing research is significant not only for understanding the ship's history but also for shedding light on the maritime activities and artefact transport practices of the early 19th century.

As archaeologists continue to study the site, the findings may provide invaluable insights into the cultural heritage of the region and the practices surrounding the transportation of ancient artifacts during a time when such practices were becoming increasingly controversial. The commitment to a detailed exploration of the 'Mentor' wreck emphasizes the importance of underwater archaeology in preserving and understanding historical narratives linked to significant events and figures from history.
