The walled town of Ste Suzanne rests on a rocky terrace above the river Erve.
The fortress was once impregnable, with William the Conqueror (of England) failing to take the town even after a two year siege. The town walls, with round towers and square bastions still stand today. A triangular range of fortifications encircle the chateau which has a medieval gateway and a 12th century keep. It has been suggested as one of the most beautiful villages in France.
