Machicoulis

Machicoulis were, basically, specially arranged loop-holes along the outer edge of the second story of a blockhouse, fortified structure, or scarp wall above the ditch of a fortification that allowed fire to be delivered downward from a covered position. They were especially useful in unflanked works or along interior angles of permanent fortification for bringing defensive fire to bear on points along the base of walls that could not otherwise be reached by fire from the work. A machicouli gallery was a bullet-proof wooden structure attached to the exterior of a fortified building that allowed defenders to fire downward onto the base of the building's exterior walls and were particularly useful when placed above doorways and large windows that might become the objects of an assault to gain entry into the building.
