A place-of-arms (Italian: piazza d'armi, French: place d'armes) is any place in a fortification where troops can gather. The term has a number of meanings, but it generally refers to an enlarged area of the covertway designed as an assembly point for soldiers, or a square in the centre of a fortress, also known as a parade ground.
