The Pnyx is a small hill west of the Acropolis whose summit was levelled in the 6th century BCE to serve as the meeting place of the Athenian Assembly. The stone speaker's platform — the bema — is still visible, cut into the bedrock and facing a curved auditorium that could hold thousands of citizens.
It is one of the most historically loaded places in the ancient world and one of the quietest. There are no tickets, no fences, no fellow tourists. Walk up from the path that climbs Filopappou Hill, find the platform, and stand on the spot where Pericles delivered his Funeral Oration. The view of the Acropolis is a separate reward.
