Object description

Ouvrage Castillon is a work of the Maginot Line's Alpine extension, the Alpine Line, also called the Little Maginot Line. The ouvrage consists of one entry block, two infantry blocks, and two artillery blocks in a narrow ridge just to the west of Castillon, Alpes-Maritimes. It was built on the original site of Castillon, destroyed by an earthquake in 1887. It is the next gros ouvrage in the line to the north of Ouvrage Sainte-Agnès, and is within firing range of the Mediterranean coastline.
