Thanos was named after a wealthy landowner called Athanasios, who came from the Arcadian village of Thana. The community was once located near the sea, but the residents relocated inland due to fears of pirate attacks.

The village church, Agia Paraskevi, is a three-aisled basilica which was erected at the cost of the community in 1890 on the site of an older one, the masonry of which was integrated into the new church. The exonarthex’s five arches are supported by monolithic columns.

With its unusual rock formations creating the setting for the long sandy seashore, Thanos Beach is one of Lemnos’ most attractive beaches.
