Arch of Triumph
A structure in the shape of a monumental archway, usually built to celebrate a victory in war. The arch is invariably a free-standing structure, quite seperate from city gates or walls. In its simplest form a triumphal arch consists of two pillars connected by an arch, crowned with a superstructure or attic on which a statue might be mounted or which bears commemorative inscriptions. More elaborate triumphal arches have more than one archway, typically three or five of varying sizes.
