What is "machicolation"?

Machicolation is an architectural feature commonly found in medieval castles and fortifications, designed for defensive purposes. It consists of a projecting structure, often located above an entrance or wall, with openings or holes through which defenders could drop projectiles or boiling liquids onto attackers below.

Machicolations are often seen on the tops of towers or gatehouses, enhancing both the security and visual appeal of the structure. They are a distinctive element of medieval architecture, reflecting the military needs of the time.
