On the southern slope of the Acropolis is an ancient stone theater, known as the Odeon of Herodes Atticus (Herodion). It was built in 161 AD. by the Athenian magnate Herod Atticus in honor of his late consort Regilla. Initially it was an amphitheater with a steep slope and a three-story stone front wall, the roof was made of expensive Lebanese cedar wood. The structure is very well preserved to this day, with the exception of statues in the niches and multi-colored marble cladding. The odeon was used for musical concerts and accommodated 5,000 spectators. In 1950, the theater was reconstructed; white Pentelic marble was used for cladding. Odeon today amazes with its magnificent acoustics. The Odeon of Herodes Atticus is the venue for the Athens Festival, which is held annually from May to October.
