What makes the Ancient theater of Epidaurus special is the renowned acoustics. Scientists attribute this to several factors: the natural lime stone used in the construction of the theater which carries sound better than marble, the semi circular shape embedded in a hill which amplifies sound and the reflection from the visitors which, with 15.000 when full seemed to be just the right amount. Some still say, it’s simply a fortunate accident, but one can stand on the round platform or proscenium and even a whispered word can clearly be heard in the top tier of the seats.
