Where were plays performed in 400 BC Greece?

In 400 BC Greece, plays were primarily performed in theaters built specifically for this purpose. These theaters were often constructed on hillsides, taking advantage of the natural slope for seating and acoustics. Some of the most famous examples include:

* The Theatre of Dionysus in Athens: This theater was dedicated to the god Dionysus and was the site of the annual dramatic festivals, including the City Dionysia, where playwrights like Sophocles, Euripides, and Aristophanes competed.

* The Theatre of Epidaurus: Known for its exceptional acoustics, this theater was located in the Peloponnese and was used for religious festivals and dramatic performances.

* The Theatre of Delphi: Built on the slopes of Mount Parnassus, this theater was used for performances during the Pythian Games, a major religious festival held in honor of Apollo.

It's important to note that while these theaters were the primary locations for dramatic performances, plays were also performed in other public spaces like marketplaces and agoras (public squares), particularly for smaller-scale performances or informal gatherings.
