<Location> Roman Agora, Athens, Attica, Greece
Public Latrine at the north eastern corner of the Roman Agora site, constructed in the first century CE. There were seats for 68 people. It used to be a covered building with open atrium for ventilation and liting. The filth was carried away with water.
This is a part of the toilet seats. In this photo it is put on the ground, but originally it was at the top of the bench like structure. Man might use it standing in front of the hole, or seating on it. It is not clear if women could use these toilets, too.
There are remains of Roman public toilets in Corinth, too.
