Duroc square is depicted by a triangular shape and arcaded houses. The 16C Maison des Sept Péchés capitaux (House of the Seven Deadly Sins), with its lovely caryatids and Renaissance turret, is where the dukes of Lorraine used to reside. The Renaissance-style fountain in the centre of the square actually dates back to 1931 and was built to commemorate the service of American medics during WW1.
