Dodona in Epirus in northwestern Greece was the oldest Hellenic oracle, possibly dating to the second millennium BCE according to Herodotus. The earliest accounts in Homer describe Dodona as an oracle of Zeus.

Situated in a remote region away from the main Greek poleis, it was considered second only to the Oracle of Delphi in prestige.

The Theatre of Dodona is one of the largest theatres in Greece (18.000 seats) and was built during the 3rd century BCE.

It is comprised, like all ancient theatres, of a koilon (spectators' seats), a stage, and an orchestra whilst there was also a Doric colonnade.

There may possibly also have been a wooden construction in front of the stage. Its walls extend 21 meters in height and are supported by strong towers.
