Cabane Vauban, Military lookout post on coastal cliffs in Carolles, France.

Cabane Vauban is a small rectangular guard post on the cliff top above the Baie de Granville, on the chemin des douaniers in Carolles. Its walls and steep roof are built of dark hornfels rubble, with lighter, larger granodiorite blocks framing the door; it has a chimney, a window and a firing slit. The open doorway sits left of centre in the front wall, and a low chimney rises at the left end of the ridge.

This structure was built in the early 1700s as part of a network of military posts designed to protect the coast from invaders. Soldiers used fire and smoke signals to communicate warnings about approaching enemy vessels to neighboring positions.

The site forms part of the GR 223 hiking network, connecting multiple historical military posts along the Normandy coast. Today it serves as a landmark for visitors exploring this region's defensive heritage on foot.

The site is accessible via a hiking trail approximately 5 kilometers from Carolles, with moderate elevation changes throughout the walk. Sturdy footwear and plenty of time are recommended for this coastal route.

The building's walls and roof are made of dark hornfels rubble, while the door and window frames use lighter granodiorite blocks. It originally had a door, a window and a firing slit, plus a chimney. The roof was redone in 1953 and the walls restored in 1990.
