Athens. Greece. View of the foundation ruins of the public latrines or toilets (Vespasiane) that served people who visited the ancient Roman Agora. Dating from the 1st century BC, the roofed rectangular shaped building had toilets seats for 68 people, on all inner sides of the structure. In its center was an open air atrium for ventilation and light. Running water flushed away the waste via a deep canal.
