Pnyx

The Pnyx is a hill or hillside in central Athens, the capital of Greece. Beginning as early as 507 BC, the Athenians gathered on the Pnyx to host their popular assemblies, thus making the hill one of the earliest and most important sites in the creation of democracy.

The Pnyx is located less than 1 kilometre west of the Acropolis and about 2 km south-west of the Syntagma Square in the centre of Athens. The "mainly natural hollow" was first used from before 500 BC to perhaps 404 BC, when the arrangement was changed by adding a retaining wall below the speakers' platform, with the space between filled with earth.The Pnyx was probably the prototype for the Greek theatre auditorium, with the late form perhaps reflecting changes in theatre design.
