The western area of the abbey grounds was accessed through a gatehouse positioned at the northeastern end of the western wall, from which a 25.7 metre stretch of wall, standing two metres high, extends eastward. Where this wall has collapsed, two grassy mounds littered with protruding stones trace its original path towards a tower that projects from the northwestern corner of the abbey’s nave. Curiously, this tower shows no evidence of being tied into the enclosing wall, suggesting that later construction work may have disrupted the original defensive circuit.

Southwest of the gatehouse, another significant length of wall stretches for over 50 metres, incorporating the remains of a long rectangular building that cleverly used the enclosing wall as its rear face. This section features four arrow loops set within wide, inwardly splaying embrasures, topped by remnants of a wall walk complete with traces of a parapet at its northern end. The southern wall appears to have undergone substantial rebuilding over the centuries, with internal arcading at its western end that once supported another wall walk. Midway along this southern boundary, the foundations of another rectangular building can be traced, whilst further east, the wall takes a sharp turn where a small defensive structure once stood, its arrow loops still visible in the southern and western walls.

The eastern enclosing wall runs for nearly 67 metres along a north northeast to south southwest axis, though today it’s heavily overgrown with brambles and has partially collapsed towards its southern end. Near the southeastern corner of the precinct, remains of yet another rectangular building can be found, measuring just over 13 metres in length. The layout suggests that the abbey grounds were divided into two distinct areas: an outer precinct to the west and an inner precinct encompassing the eastern and southern areas around the main abbey buildings. A now mostly vanished structure once connected the western end of the south range, effectively separating these two zones and controlling movement between the secular and sacred spaces of this important medieval monastery.
