Archaeological site Odeon of Agrippa in Municipality of Athens

You're standing in the middle of the ancient Agora of Athens, at what was once one of the most impressive buildings in the city: the Odeon of Agrippa. Not much of it survives, so you'll need a bit of imagination. This spot used to be open space at the heart of the marketplace. Around 15 BC, a huge covered concert hall went up right here. It was a gift to the people of Athens from Marcus Agrippa, the Roman general who was Emperor Augustus's right-hand man. Agrippa actually lived in Athens for a few years around then.
