St Osyth's Priory: Garden Walls located to the east and west of the Rose Garden, south of the Darcy Wall

St Osyth's Priory features garden walls located to the east and west of the Rose Garden, south of the Darcy Wall. The west wall, approximately 3-4 meters high, is built of Septaria, rubble, and brick, including some red brick, and has a stone capping. It is about 64 meters long and connects the east range of the Gatehouse to the south with the front wall of the second Lord Darcy’s mansion to the north, where a later segmental archway with a wrought iron gate has been added. Near the southern end, there is a 4-centred archway made of chamfered stone, complete with a hood mould and a parapet of Septaria and brick above on the west face. The east face features a secondary brick arch above the opening, flanked by stone buttresses with tiled copings. Adjacent to the east range of the gatehouse, the west face includes a lean-to constructed of similar materials with a pantiled roof.

The east wall, also 3-4 meters high, is approximately 83 meters long and connects the precinct wall to the south with the Darcy tower to the north. It is made of red brick laid in English bond, has a later soldier capping, and features an arched doorway inserted at the southern end.
