A remarkable site on the cliffs near the village of Saint Leger, to the west of the port town of Saint-Valery-en-Caux.
There were three observation and fire control posts on the cliffs here, originally of French origin but adapted by occupying German forces, although one now rests in pieces at the bottom of the high cliffs today.
The remaining two positions are on borrowed time given their proximity to the edge of the crumbling chalk cliffs and are now too dangerous to visit.
Behind the buildings are the remains of the Saint Leger bell tower, a 16m high church steeple-like building which was constructed in 1640 but partially destroyed during the French Revolution.
Standing proud on the hilltop to the east of Saint-Valery-en-Caux, Erwin Rommel believed the tower would act as a directional landmark for Allied aircraft and ordered it to be levelled on February 14, 1944, leaving the structure you can see today.
