Epidaurus sits a few miles off the Saronic coast. Apollo was worshiped on the site in Geometric times, but with the rise of his son Aesclepius (god of healing and medicine) in the Archaic period, Epidaurus came to be known as the "birthplace" of Aesclepius (ca. 500-475 B.C.). First thought to be a gymnasium, this banqueting hall had a ramp leading up north to a Doric gateway. It was probably built around 300 B.C. and was used for ritual meals called thusia. After animals were sacrificed on altars, they would be consumed here.
