An arch is an edifice consisting of a stone semi-circle set atop pillars. It is a period charge, found in the canting arms of Arches, c.1295 [ANA2 11]. The default form is with a single arch, as in the illustration, but double and triple arches are also possible: the double arch supported by three pillars, the triple arch atop four pillars, &c.
In Society armory, an “arch stooped” has the pillars resting on a plinth; a “pointed arch” has an ogive-shaped archway. Society armory also has the “triumphal arch”, a monument erected by the Imperial Romans. For related charges, see dolmen, torii.
