Seaton Hall with Attached Ruins

Seaton Hall is a house with adjacent ruins of a Benedictine nunnery, founded around 1190. The house itself dates from the 16th century and underwent restorations in the 19th century. It is constructed of stone rubble with ashlar dressings and has a slate roof. The building is two storeys high and has a U-shaped plan, with the remains of the east end of the chancel at the end of the east wing.

The east wall of the chancel features three lancet windows, with the central window being complete. It has an internal continuous hoodmould with nail-head mouldings and reset cinquefoil and trefoil designs in the spandrels. The south wall contains small recesses and parts of trefoil arches, which may have been sedilia, along with a corbel in the angle at the top of the remaining wall.

The north elevation of the south wing has three bays with three-light single-chamfered mullioned windows that include transoms, while the first bay has single lights. There is one label mould present. The central entrance features a Tudor head and there is a cross-axial stack.

The east wing's west elevation has two bays with a single-storey end bay, featuring two- and four-light windows along with two-light windows on the first floor. The east elevation has two-light windows with labels, as well as stair and first-floor windows with transoms and an attic light; the rest of the elevation has casements and a small wing.

On the south elevation, there are transomed windows arranged in a pattern of 2:2:3:2 lights, with a small square light located between the third and fourth bays of the first floor. A corbelled lateral stack has an octagonal shaft and a pointed entrance. The west elevation features a large projecting lateral stack, a ground floor transomed window of three lights, and canted bay windows; the first floor has two- and four-light windows, along with an attic light.

The north end of the west wing has three-light windows, with the ground floor window featuring a relieving arch and the first-floor window having a transom and label. The east elevation of the west wing has two blocked entrances and two-light windows on the first floor, along with a cross-axial stack. The interior reflects the 19th-century restoration.
