Thar (river)
The Thar is a small river of France, in the administrative region Basse-Normandie, département de la Manche. It is only 25 km (16 mi) long, rising to the east of La Haye-Pesnel and emptying into the Bay of Mont Saint-Michel, in the English Channel.
In the Middle Ages the Thar formed the traditional boundary between the Cotentin to the north and the Avranchin to the south.
