Origin and history

The blushing oven on the Pointe du Roc, located in Granville, Normandy, is an 18th-century historical monument. This casemate reverberator oven, probably inspired by the Fourcroy model (1788), was used to heat cannon pellets before firing, a technique aimed at increasing their destructive power. He is located near the guard corps of Saint-Pair, highlighting his strategic role in the coastal defence of the region.

The building consists of a large vaulted room in a cradle, accessible by a door to the south and a curved opening to the west, partially walled. This opening gives access to a corridor leading to a small rectangular vaulted room. The ensemble reflects a functional architecture, adapted to its military use. The oven was registered as a Historical Monument by order of 27 February 1987, attesting to its heritage importance.

The location of the oven, on the tip of Roc, reinforces its link with the maritime and defensive history of Granville. This type of structure was essential in the coastal fortification systems of the eighteenth century, a period marked by frequent naval conflicts and innovations in siege techniques. The oven is now owned by the commune of Granville, and its state of conservation allows you to appreciate its original architectural features.
