Epidaurus

The most acoustically perfect building ever constructed and the oldest functioning theatre in the world — Epidaurus (Argolis, Peloponnese, Greece; UNESCO WHS 1988) contains a 14,000-seat Greek theatre from 350 BCE whose limestone orchestra can project a whisper to the topmost tier without any amplification, and which hosts live performances of ancient Greek drama every summer in the Athens Epidaurus Festival.
