Porch, a building forming an enclosure or protection for a doorway. In mediæval and Elizabethan architecture the porch was very common in domestic architecture. In churches it was almost universal in England, most often on the south side of the nave, of stone or flint-work (in East Anglia), but sometimes also of wood. In France many splendid porches or portals remain; they are amongst the most beautiful specimens of mediæval art. See also GALILEE.
