Located on the fertile Argolid plain of the east Peloponnese and blessed with a mild climate and natural springs, the sanctuary of Asclepius at Epidaurus was an important sacred centre in both ancient Greek and Roman times.
Epidaurus was named after the hero Epidauros, son of Apollo. Inhabited since Neolithic times, the first significant settlement was in the Mycenaean period.
Earlier regional worship of the deity Maleatas evolved into the later worship of Apollo, however that one of Asclepius was the most popular, as the Epidaurians believed he was possessing great healing powers and also that of prophecy. The god was visited from all over Greece by those seeking alleviation of their ailments by either divine intervention or medicines administered by the resident priests.
Today, the magnificent theatre that stands next to the Sanctuary of Asclepius, renowned for its acoustics, is still in active use for performances during the Epidaurus Festival.
