The Ancient Theatre of Epidaurus is a theatre in the Greek city of Epidaurus, located on the southeast end of the sanctuary dedicated to the ancient Greek God of medicine, Asclepius.
It is built on the west side of Cynortion Mountain, near modern Lygourio, and belongs to the Epidaurus Municipality. It is considered to be the most perfect ancient Greek theatre with regard to acoustics and aesthetics.
The monument retains the characteristic tripartite structure of a Hellenistic theatre that has an theatron, orchestra, and skene. During Roman times, the theatre (unlike many Greek theatres) did not suffer any modifications.
