The Urinals of the Museu Naçonal do Azulejo (National Tile Museum)

This museum "is located in the former convent Madre de Deus in Lisbon, Portugal".

This picture was submitted by an independent contributor. He writes: "For several hundred years Portugal has been famous for its tiles... While it's understandable that a convent might never have had any urinals, it seems strange that a museum dedicated to porcelain would have installed steel urinals."
