Ancient Theater of Epidaurus
This theater is one of the most important archaeological sites in Greece. In terms of its perfect acoustics and fine structure it is regarded as the best preserved theater in Greece. Its perfect acoustics allows you to hear even the sound of a pin dropping while sitting on the top of the stairs. The rows of limestone seats filter out low-frequency sounds and amplify high-frequency sounds from the stage. It was built by the architect Polykleitos in the 4th century BC. Originally the theater had 34 rows of seats, divided into 34 blocks by stairs, that can seat up to 14,000 people. This ancient theater is the perfect example of classical theater with an orchestra and the circular area. Every summer very important Greek festival, known as Athens-Epidaurus Festival, takes place at the theater.
