The 1,200-year-old Allouville oak tree was the star of a comedy by Serge Pénard, released in 1981. It has been venerated since the parish priest slipped a pious image dedicated to the Virgin into a crack in the tree in 1696. The hollow trunk is covered with wood tiles, and a small bell tower topped with a cross surmounts it. The oak survived the French Revolution, was amputated by lightning in 1912 but has kept producing leaves and acorns each year.
