Ancient Greek Theaters & Odeon's

Ancient theaters had no roofs but odeon's did. Acoustics were generally considered to be superb in each. Epidavros is an example still in use today. Ancient roofs were usually supported/constructed of wood so most roofs, if not all, have been destroyed by fire over the centuries.

Below is the Odeon of Herodicus Atticus in Athens just under the Acropolis which holds 5,000 people and is still in use today and as a theater as well. Next to it is the much larger Theater of Dionysus but in an unusable condition. The Theater of Dionysus was the first theater ever essentially that I know about anywhere in the western world.

Another famous ancient Greek theater is in the Peloponnese, at Epidavros, a couple of hours from Athens, and presentations of various kinds, which you can attend, are held there during the summer. These presentations are usually in ancient Greek however.
