The House of the Tiles is a monumental Early Bronze Age building (two stories, approximately 12 x 25 m) located at the archaeological site of Lerna in southern Greece. It is notable for several architectural features that were advanced for its time, notably its roof covered by baked tiles, which gave the building its name. The building belongs to the "corridor house" type.
The site was excavated by the American School of Classical Studies under the direction of John Langdon Caskey of the University of Cincinnati.
The structure dates to the Early Helladic II period (2500–2300 BC) and is sometimes interpreted as the dwelling of an elite member of the community, a proto-palace, or an administrative center. Alternatively, it has also been considered to be a communal structure, i.e., the common property of the townspeople. The exact function remains unknown due to a lack of small finds indicating the specific uses of the building. The house had a stairway leading to a second story, and was protected by a tiled roof. Debris found at the site contained thousands of terracotta tiles having fallen from the roof. Although such roofs were also found in the Early Helladic site of Akovitika and later in the Mycenaean towns of Gla and Midea, they only became common in Greek architecture in the 7th century BC. The walls of the "House of the Tiles" were constructed with sun-dried bricks on stone socles.
Carbon-14 dating indicates that the House of the Tiles was finally destroyed by fire in the 22nd century BC. Not long after the destruction, the place was cleared in such a way as to leave a low tumulus over the site. The destruction of both the building and the building site was first attributed by John Langdon Caskey to an invasion of Greeks and/or Indo-Europeans during the Early Helladic III period. In reality, the elaborate structure of the tumulus built by the Early Helladic III people over the ruins of the House of the Tiles indicates a "showing of respect for their predecessors that one would not expect of invaders of a different culture."
