Stuart Hall, Stuart Hall Demense, Mountjoy Road, Stewartstown, Co Tyrone, BT71 5AE

Stuart Hall was a country house built around 1760 by Andrew Thomas Stewart, who became Viscount Castle Stewart in 1793 and Earl Castle Stewart after 1800. The original house was described in the Post Chaise Companion of 1786 as "a most superb edifice with extensive and beautiful parks and demesnes".

The house was a regular five-bay Georgian structure, measuring 88 feet across its front and 56 feet deep. It was designed to be two storeys over a basement. The plain but finely detailed exterior was harled throughout, with a sandstone basement course and quoins. A fluted string course ran between the ground and first floor. The main door was tripartite, with an entablature supported on Tuscan columns. The upper floor comprised six bays.

Inside, the house featured a square hall with an arcade opening at the back to the staircase, which had openwork banisters and a carved rail.

In 1860, the house was extended with an L-shaped Georgian wing and a Baronial tower to the south-east, a somewhat ill-conceived addition featuring mullioned windows, a corner stair-turret, and angle bartizans at roof level. A castellated parapet was applied to the original section in an attempt to unify the design. The tower was of crude and heavy detail.

The property was badly damaged by a bomb in 1974. The original house was demolished in the 1980s and replaced by a modern bungalow.

The estate also contained extensive outbuildings, largely contemporary with the house, arranged in a distinctive quarter-circle plan as shown on the 1833-34 Ordnance Survey map. A walled garden with a date stone of 1832 was recorded on the same map. A private Presbyterian chapel or meeting house was incorporated within the complex, likely built in the later 1800s under the 4th or 5th Earls of Castle Stewart. Decorative folly towers visible on the 1853 Ordnance Survey map complemented the Baronial additions made by the 4th Earl in 1860.
