There is substantial myth to be found in Lerna. The town was home to the Lernaean Hydra, a water snake killed by Hercules. Lerna was also one of the entrances into the underworld and the ancient Lernaean Mysteries of Demeter were celebrated there.
The House of Tiles was constructed around 2200 B.C. as a mansion for a chieftain or possibly an administration building. The building was two stories high, made of yellow brick on a stone foundation, and the roof was covered with terra-cotta tiles. It was destroyed by fire and the site was never re-built possibly out of reverence for the significance of the structure.
