Explanation:

In ancient Greece, Pnyx was the official meeting place of Eclesia, the Athenian popular assembly. At the beginning of Athenian democracy, after Clisthenes' reforms in 508 BC, the Eclesia took place in the Agora, the main "square" of the city.

Sometime in the fifth century BC, the meeting place was moved to a hill west of the Acropolis, which was called "Pnyx".

Pnyx is a hill in central Athens, the capital of Greece. It is located less than 1 km west of the Acropolis, and 1.6 km southwest of the modern city center, Syntagma Square. It is a small rocky hill surrounded by a park, with a large flat area and steps carved into its slope. In this place, the great political debates of ancient Athens were fought.
