Lerna

A prehistoric settlement near the Argolic Gulf in the Peloponnese, continuously inhabited for approximately 5,000 years from the Neolithic to the Mycenaean period (6th-1st millennium BC). Its most famous structure is the House of Tiles (c. 2500-2300 BC), a monumental Early Helladic II corridor house measuring 12 x 25 m with stone foundations, mud-brick walls, and one of the earliest fired-clay tile roofs in Greece. Excavated by John Caskey of the American School of Classical Studies in the 1950s, it yielded over 150 clay sealings from some 60 seals, suggesting early administrative functions. After its destruction by fire, a memorial tumulus 19 m in diameter was raised over the ruins.
