La Haye-du-Puits Tower
La Haye-du-Puits tower, locally known as Donjon de La Haye-du-Puits, stands near the main road through the town of the same name in the Manche department in the Normandy region in France.
Of the ancient castle of La Haye-du-Puits only this keep remains. It stands on a motte and was probably built in the 11th century by Turstin Haldup, who was of Scandinavian origin and the first baron of La Haye-du-Puits.
He and his wife Emma, sister of the Duke Guillaume, also founded the abbey of Lessay in 1056. Their son was also a benefactor of the abbey and enlarged it in 1098.
This was all the historical info I was able to find about this tower. So if anyone knows more, please mail me.
A nice keep which can't be entered because of the risk of collapse.
