Description

The garden wall and house ruins at Flemingston Manor are constructed from local lias limestone rubble, featuring dressed quoins and some ashlar elements, with part of the structure covered by a Welsh slate roof. The castellated wall stands approximately 3.5 meters high and marks the boundary between Flemingston Manor and the churchyard of the Church of St. Mark. This wall includes an arched doorway with a stile leading into the churchyard and the remnants of an early 16th-century building, which may have served as a pre-Reformation rectory.

The building consists of two sections, separated by a straight joint. The older section is in a very ruined condition, with only the rear wall adjacent to the churchyard remaining relatively intact. This external face, about 4 meters high, features a small dressed window and two small square vents. Inside, there is a large, roughly finished fireplace on the ground floor, with a window to the left looking into the later building. On the upper floor, there is a 2-centred doorway, with the window visible behind it, likely serving as a garderobe. To the right of this doorway is a large dressed stone fireplace, now obscured by ivy, indicating that this room functioned as an Upper Hall.

The secondary building, which still has a roof, features a pointed arch doorway with hollow chamfers on the gable end, along with a 2-light window and a single light window above on the main wall. Both windows are later additions, and the wall shows signs of previous openings. The rear wall is blind but has a projection for a staircase. The interior of the later section was not inspected during the resurvey, but it is known to contain a corner stone stair and a bread oven.
