Description
VDP cloches were equipped with three embrasures or crenels for direct vision, providing protection to observers. VDP cloches were also equipped with

s that allowed a greater arc of view. The cloches were embedded in a thick concrete carapace over a combat, entrance or observation block element of a largely subterranean Maginot fortification. A platform, identical to that used in the GFM cloche, was installed for the observer within the cloche. No armament was fitted. 64 VDP cloches were installed along the Maginot Line.
VP cloche
The similar VP (''Vision Périscopique'') cloche lacked direct observation ports, presenting a much lower profile. Twenty VP cloches were installed.
