<Location> Athenian Agora, Athens, Attika, Greece
The photo above is the "orchestra" (stage) of the Odeion.
This building is called the "Odeion of Agrippa" or the "Agrippieion", as it was constructed by Agrippa, Augustus' general and close ally. He must have started the construction between 16 and 14 BCE while he was staying Athens, and completed before his death in 12 BCE.
Now its only remains are some part of floor and some columns, and it is difficult to immagine how it looked like, but, as the other odeions, it must have been a roofed rectangular building. The hall measured ca. 25 metres by 25 metres, and the highth from the orchestra to the roof was about 23 meters. The capacity was about a thousand people. The remaining floor of the orchestra is conserved from Agrippa's origina building.
In the fifth century, the building was incorporated in a large private palace.
