Roman latrines in the gymnasium complex at Ancient Salamis in north-eastern Cyprus. The structure is semi-circular and at the circumference (top left) you can see the arm rests of some of the individual toilets. Apparently these latrines had a capacity for 44 people (very cosy!). In the centre would have been a fountain and water from this would have been led into a small channel in front of the users and used to flush the waste into the outlet. Pretty sophisticated for the times!
