Crenellated Walls

A masonry wall arranged with a line of loop-holes and an open or arched gallery for infantry to stand on to fire through the loop-holes. This type of wall was a particular feature of the polygonal system's detached and semi-detached scarp walls developed at the end of the eighteenth century and carried into execution during the first half of the nineteenth century. Crenellated walls were also adapted for inclusion in some bastion system fortifications designed toward the middle of the nineteenth century such as Fort Gaines and Fort Clinch both of which used crenellated semi-detached scarp walls to cover the curtains between bastionnets at the forts' angles.

Walls pierced with loop-holes were also employed within permanent fortifications to provide musket fire defense of the sally port barrier and to defend the interior of the sally port in the event that an enemy broke through the barrier.
