Ouvrage Monte Grosso is a work (''gros ouvrage'') of the Maginot Line's Alpine extension, the Alpine Line, also known as the Little Maginot Line. The ouvrage consists of one entry block, four artillery blocks and two observation blocks facing Italy. It was the largest ''ouvrage'' in the Alps 〔Kaufmann 2006, p. 17〕 It is part of the fortifications surrounding Sospel, which protect the approaches to Nice from the north. ==Description== Monte Grosso, like L'Agaisen to the southeast, features gun turrets on a commanding height, at 967 meters. Monte Grosso possesses two turrets, one of 75mm and a unique 135mm turret, both retractable. Monte Grosso was built between November 1931 and June 1935, by a contractor named Borie. The cost was 40.4 million francs, of which 4.6 million francs were for the access road.〔Mary, Tome 4, p. 29〕 *Block 1 (entry): one machine gun cloche, one grenade launcher cloche and three machine gun embrasures. *Block 2 (artillery): one machine gun cloche, one twin machine gun embrasure, two 75mm/29cal gun embrasures and two machine gun embrasures. *Block 3 (mortar): one machine gun cloche and four 81mm mortar embrasures. *Block 4 (artillery): one machine gun cloche and one twin 75mm/33cal gun turret. *Block 5 (artillery): one grenade launcher cloche and one twin 135mm howitzer turret. *Block 6 (infantry): one observation cloche, one machine gun cloche and two twin machine gun embrasures. *Block 7 (infantry): one observation cloche, one machine gun cloche and twin machine gun embrasure.
