St Johns Abbey gatehouse and precinct. <1> N gatehouse, probably C15, of St Johns Abbey, founded by Eudo Dapifer and dedicated 10th February 1115 AD. 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 is the entrance for pedestrians, also with four-centred head. Two-light upper windows and battlements. Flanking polygonal angle turrets with large crocketed pinnacles. No flushwork on the other side, one wide gateway, restored C19. <2> <3> Gatehouse is of two storeys, walls partly of rubble and partly of brick with limestone dressings. Roofs are covered with lead and tiles. Probably built C15 and has been considerably restored. Some C12 fragments are incorporated into the internal walls of the gatehouse. <4>
A geophysical survey was carried out I . All that was possible to establish was that a north-south wall, for which there is some surface evidence did exist for at least 45m, and that there is evidence for a second wall some 20 to 25m to the east of the first one, this wall turning westwards at the south of the area surveyed. There was probably also an east-west wall at the southern end of the lower grassed area.<5>
