A former fortified farm from the 15th century, the manor of Potrel, in Dragey-Ronthon, in the Manche department, today only reveals a courtyard entrance guarded by two turrets pierced with loopholes and an orthogonal dovecote. Partially listed as a Historic Monument, it now has a more recent main building with a hall of honor decorated with a set of woodwork and painted beams from the end of the 17th century.
