The ouvrage consists of three entry blocks (including a terminal for an
aerial tram) with a guard block, one infantry block, two artillery blocks and one observation block facing
Italy. The mountaintop position is unusual in having two 75 mm gun turrets: due to restricted fields of fire, most Alpine
ouvrages had their guns in
casemates. Mont Agel, with its commanding site, could make appropriate use of turreted guns. A 145 mm gun turret was planned, but not built. •
Block 1 (personnel entry): no armament. •
Block 2 (materials entry): no armament. •
Block 3 (aerial tram entry): no armament. •
Block 4 (entry guard block): two machine gun ports and
one machine gun turret, intended to defend the three entry points in Blocks 1–3. •
Block 5 (artillery turret block): two 75mm/1933 guns in one retractable turret. •
Block 6 (artillery turret block): two 75mm/1933 guns in one retractable turret. •
Block 7 (infantry block): one machine gun/observation turret. •
Block 8 (observation block,
Observatiore Est de Mont-Agel): one machine gun port, one machine gun turret and one machine gun/observation turret. Block 8 is not connected to the rest of the complex by a gallery. The Maginot blocks are concentrated in a relatively small area on the west side of the summit plateau, to the north of the Séré de Rivières
reduit. They are not used by the French Air Force installation.
Observation posts The observatory Mont-Gros de Roquebrune is an observation block intended to spot the fall of shot for Ouvrage Mont Agel. Located near
Roquebrune, the post is at a lower altitude and closer to the sea than Mont Agel, and affords a clear view of the coast and sea at times when Mont Agel is in or above the clouds. The post has two blocks: an entry block with a machine gun port and the observation block with one
machine gun/observation cloche. Four other observation posts are associated with Mont Agel, including Mont-Gros principal, Mont-Agel abri nord and Cime de Cabanelles. The Observatiore Est de Mont-Agel is a larger post designed and constructed to CORF standards, sometimes called Block 8 of Mont Agel even though it was not connected to the
ouvrage. Two instruction casemates were built at Mont Agel, facing north. A 75mm gun casemate is located between the
réduit and the
ouvrage on the southwest corner of the plateau, while an 81mm mortar casemate is located at the north end. ==Forteresse du Mont Agel==
