The village is located at the confluence of the Dourdou de Conques and Ouche rivers. It is built on a hillside and has classic narrow Medieval streets. As a result, large vehicles (such as buses) cannot enter the historic town centre but must park outside. Consequently, most day visitors enter on foot. The town was largely passed by in the nineteenth century, and was saved from oblivion by the efforts of a small number of dedicated people. As a result, the historic core of the town has very little construction dating from between 1800 and 1950, leaving the medieval structures remarkably intact. The roads have been paved, and modern-day utility lines are buried.
The town is situated in a valley. Its name originates from Old French conche basin (Latin concha shell).[2]
