Survey of St John's Abbey Gate by Pevsner 'N Gatehouse, dating probably from C15. It is a splendid piece of display, characteristically more ornate to the outer world than to the Abbey precincts. The outer facade is of flint with a great deal of flushwork decoration, chiefly shafts and blank crocketed arches. Tall carriageway with four centred head and tall niches above and to the left and right. Below the right niche the entrance for pedestrians, also with four centred head. Two two-light upper windows and battlements. Flanking polygonal angle turrets with big crocketed pinnacles. No flushwork on the other side and only one wide gateway with a much simpler arch moulding. Inside the gateway is a star-shaped lierne-vault. The whole gatehouse was extensively restored on the 19th century'.<1> Note that this description was updated in Bettley & Pevsner 2007.<2>
