The Tour de Moricq has always been surrounded by legends. It was once said that an underground passage would connect it to the Angles church. Also, strange signs engraved on the north facade are said to be a plan to find a treasure buried in its depths. According to tradition, it would be a golden chest which would only be accessible at the time of the Sanctus of Midnight Mass, at Christmas. According to another legend, the tower was built by fairies in a single night.

Classified as a Historic Monument in 1915. Originally a sentinel at the edge of the mainland, then a prison and finally a granary, the Moricq Tower has suffered greatly, throughout its history, from the repeated insults of time and men. For more information on visits: 02 51 97 56 39

The Plessis menhirs were once an equilateral triangle of three large menhirs, each 100 meters apart, but now only two remain. The southern menhir is much smaller than its neighbor. There is an information board that tells the story of these historical monuments.
