Ouvrage Roquebrune is a work (gros ouvrage) of the Maginot Line's Alpine extension, the Alpine Line. The ouvrage consists of one entry block, two artillery blocks and one observation block facing Italy. The fortification is located on the heights behind Roquebrune at an elevation of 321 meters overlooking Cap Martin and the bays of Roquebrune and Menton. The ouvrage was manned by 293 men of the 58th Demi-Brigade Alpin de Forteresse (DBAF), supported by the 157th Régiment d'Artillerie de Position (RAP), under the command of Captain Gayot. [1]
The ouvrage was built between November 1931 and July 1933 by Thorrand et Cie., at a cost of 20.3 million francs. [2]
Block D was unbuilt, planned for four 81mm mortars, and Block E, also unbuilt, was planned as an infantry block. The subterranean connecting galleries, ammunition magazines, usine and barracks are arranged in a branching pattern. Four observation posts are associated with Roquebrune, including the Abri Est de Mont-Gros and the Observatoire Croix-de-Muratoire. [7]
Block 3 is essentially the same as the large artillery casemates built by CORF for the main Maginot line in northeastern France, with 75mm guns on the upper level and 81mm mortars firing upwards out of the pit in front of the guns. The block is sunk into the ground, compared to the more typical batteries in the Alps, which were usually built into the side of a cliff or rock wall. [8] Block 2 fired 599 rounds of 75mm shells and 770 81mm mortar rounds in June 1940. [4]
Roquebrune retains its peacetime barracks overlooking the Mediterranean. The barracks have recently been restored. [9] The ouvrage is occupied by the maintenance department of the local parks and recreation authority. The interior is not accessible but is in good condition, while the exteriors of the blocks are easily accessible. [1] [4] [5]
The observatory Mont-Gros de Roquebrune 43°45′58″N7°26′35″E / 43.76611°N 7.44306°E is an observation block intended to spot the fall of shot for Ouvrage Mont Agel, and is more closely associated with that fortification. [10]
Ouvrage Latiremont is a gros ouvrage of the Maginot Line, located in the Fortified Sector of the Crusnes, sub-sector of Arrancy. It lies between the gros ouvrage Fermont and the petit ouvrage Mauvais Bois, facing Belgium. The village of Doncourt-Cités is nearby. Latiremont was active in 1939-1940, coming under direct attack in late June 1940. It surrendered to German forces on 27 June. After renovations during the Cold War, it was abandoned.
Ouvrage Mont des Welches, a gros ouvrage of the Maginot Line fortifications, is part of the Fortified Sector of Boulay. It comprises two entrance blocks, one infantry block, one artillery block, one observation block and two combination blocks. It is located between petit ouvrage Coucou and gros ouvrage Michelsberg, facing Germany. Relatively small for a gros ouvrage, Mont des Welches saw a brief period of sharp action in June 1940, when German forces moving along the rear of the Maginot Line engaged the position without success. After modest renovations in the 1950s, Mont des Welches was abandoned in the 1970s.

It is located between gros ouvrage Mont des Welches and petit ouvrage Hobling, facing Germany. Michelsberg did not see significant action in the Battle of France until June 1940, when it was attacked from the rear by German forces that had bypassed the Maginot Line. It successfully resisted these attacks, but was compelled to surrender in accordance with the 25 June 1940 armistice. After the Second World War it was renovated as a Cold War fortification against a potential Soviet invasion, then abandoned. It is now operated as a museum, and may be visited.
