Athens (Greece)

Drain to the Eridanos

At the beginning of the 4th c BCE two branches were added to the Great Drain immediately south
of the Tholos, one to the southeast and one to the southwest, to bring rainwater and waste from
a broader section of the Agora into the main channel. In late antiquity the statue of the emperor
Hadrian, set up along the “West Street”, was used as a cover slab for the drain.
