PAVILION, in Architecture, signifies a kind of turret or building, usually insulated, and contained under a single roof, sometimes square, and sometimes in form of a dome;
and it is so called from the resemblance of its roof to a tent. Pavilions are sometimes projecting pieces in the front of a building, marking the middle of it; but sometimes the pavilion flanks a corner, in which case it is called an angular pavilion. The Louvre is flanked with four pavilions. These are usually higher than the rest of the building. Pavilions built in gardens are commonly called summer-houses, pleasure-houses, and the like. Some castles or forts consist only of a single pavilion.
