Sanctuary of Asklepios at Epidaurus
The most acoustically perfect theatre in the history of architecture and the premier sanctuary of healing in the ancient Greek world — Epidaurus (Argolid, Peloponnese; UNESCO WHS 1988) combines the greatest surviving example of ancient Greek theatre design (the 14,000-seat Theatre of Polykleitos the Younger, 4th century BCE) with the ruins of the Asklepion where the sick and injured of the ancient world came to be healed by the god Asklepios.

Key facts
- The Acoustic Secret: the most precisely EpidaurusTheatre single limestone seat filter low frequency noise voice high frequency travel unimpeded Georgia Tech 2007 whisper coin match 59m audible last row UNESCO heritage — the most extraordinary acoustic engineering of the ancient world: the acoustic research (Georgia Tech researchers (Nico Declercq and Cindy Dekeyser) published a study in 2007 CE demonstrating that the corrugated limestone surface of the seating acts as a complex acoustic filter; the limestone rows absorb low-frequency sounds (crowd noise, wind) while reflecting high-frequency sounds (the human voice) upward toward the back rows; the effect was almost certainly not planned by the architect (Polykleitos did not know acoustic physics in the modern sense) but was the result of intuitive optimization of the hillside seating material; the result is that in total silence, a coin dropped at the center of the orchestra is audible in the highest row; in modern use (the Epidaurus Festival, held every summer since 1955 CE), concerts and theatre performances are staged in the theatre without amplification (approximately 15,000 audience members per performance; the back rows are 59m from the stage))
