Battlements
Return to features index
Battlements are fortified parapets at the top of castle walls or towers. They feature an alternating pattern of solid raised sections (merlons) and open gaps (crenels), allowing defenders to launch projectiles while remaining sheltered from enemy fire. This defensive design is also known as crenellation.
The Components of a Battlement:
Merlons: The solid, upright sections of the stone wall. They provide full-body cover for soldiers and are sometimes pierced with narrow slits (arrow loops) so archers can shoot without exposing themselves.
Crenels (Embrasures): The regularly spaced gaps between the merlons. Defenders would step in front of these openings to aim and fire, then quickly step back behind the merlons to reload.
Wall-Walk (Chemin de Ronde): The elevated passageway running directly behind the battlements, allowing the garrison to move quickly along the perimeter.
As medieval siege weapons and weaponry evolved, architects added even more specific features to battlements to increase the lethality of the fortifications:
Arrow Loops (Slits): Narrow, vertical slits cut directly into the merlons, allowing archers to shoot outward while remaining completely protected behind stone cover.
Machicolations: Overhanging, bracketed stone galleries with openings in the floor. These allowed defenders to drop heavy stones, boiling water, or burning liquids directly on top of attackers at the base of the wall.
Hoardings: Temporary, roofed wooden galleries built outward from the battlements, also used for dropping objects and protecting the wall-walk during a siege.
Function and History:
While battlements started as a functional necessity, by the later Middle Ages they became a widely used status symbol. In medieval England, for example, lords had to acquire a royal license to crenellate before adding battlements to their properties. In later centuries—and throughout the Gothic Revival architectural movement—battlements were frequently built purely as decorative motifs on churches, secular buildings, and manor houses with absolutely no military function.
