22 Lislaird Road, Mournebeg, Castlederg, Co Tyrone, BT81 7UG

Lisnacloon House is a large early 19th-century country residence standing on the west side of Lislaird Road. It is three bays wide, two storeys over a basement, with an attic, and is L-shaped on plan with a return to the left side of the rear elevation. Despite being partially derelict, the house retains its original rather austere late Georgian character, though it has suffered the loss of some original features and has undergone at least two significant phases of remodelling — one around 1860 and a further refitting around the mid-20th century, the latter including what appears to be a remodelled or relocated entrance.

The roof is half-hipped natural slate with rolled clay ridge tiles and brick chimneystacks on the cross walls. Rainwater goods are aluminium, carried on drive-in brackets over corbelled eaves. The external walls are dry-dashed, with a smooth cement-rendered plinth and quoins.

Windows are mostly 6-over-6 and 1-over-1 timber sliding sashes, all set within slightly projecting smooth-rendered surrounds with sandstone sills. The principal, south-facing garden elevation is symmetrical, with a cement-rendered platband dividing the two floors, and five windows to each floor. The central ground-floor window is wider and lower than the others, suggesting it may originally have been a door opening. Ground-floor windows on this elevation are boarded over; those to the first floor are 1-over-1 sashes. The west elevation has three irregularly spaced windows to the first floor, the rightmost being a 3-over-1 sash; the ground floor was inaccessible due to dense vegetation at the time of survey. A high stone wall abuts the building at the extreme left of this elevation. The rear elevation is partly closed by the return wing at the right; the exposed left and central bays each have one window per floor. The return has two windows to each floor on its east face, and a boarded door and window opening on its north face.

The east elevation is the most architecturally detailed and now serves as the main entrance front. It features a door with six raised-and-fielded bolection-moulded panels — the central two glazed and boarded — surmounted by a geometric fanlight, all contained within a projecting cast-concrete surround with a cast cornice and fluted panel detail. This elevation is otherwise plain, with the exception of a 3-over-3 window to the attic level and a diamond-shaped panel in the render at first-floor level. The new side entrance introduced here has reduced the building's overall architectural interest.

To the rear is a yard, now grassed and overgrown, enclosed by several stone outbuildings, some of which are ruinous, and by a high rubble-stone garden wall. The outbuildings are a mixture of two-storey and single-storey structures with pitched slate roofs and roughly coursed random rubble walling. They include a two-storey byre and loft at the northwest, where most openings have timber lintels but the byre entrance has rubble voussoirs, and a long single-storey coach and stable range to the east in coursed rubble stone, with rubble voussoirs to most openings, one inserted square-headed opening with a timber lintel, and a segmental-headed coach arch at the right. Doors throughout are timber-sheeted.

The house is approached from the east by a long, partially gravelled avenue marked at its junction with the road by the remains of a stone gatescreen, consisting of dressed limestone pillars and squared rubble curved screen walls. The avenue is lined with conifers and the setting as a whole is unspoiled. The large farmyard to the rear attests to what was once a prosperous establishment.

Much internal fabric survives from before the mid-20th-century refitting. A 1933 valuation record describes the ground floor as containing three rooms, a kitchen, bathroom and WC, one reception room used as a store, and further store rooms; the first floor had seven bedrooms and two stores; and the second floor two unceiled attic rooms. The 1935 valuer noted that the kitchen was too large and practically unused, cooking being done on an oil stove, while the reception rooms were described as large and well-lit, and some bedrooms as good.

The house appears on the first edition Ordnance Survey map of 1832–33, at which point it is uncaptioned, though a schoolhouse is shown to the north of the site. By the second edition of 1854 it is named as Lisnacloon House, and a gate lodge is shown to the north alongside a formal garden; corn, flax, and tuck mills appear to the east. By the fourth edition of 1952 the house is recorded as a rectory, with the lodge and school still shown.

The Ordnance Survey Memoirs record the house as "the residence of James Anderson Esq (land agent to Sir Robert Ferguson)" in Lisnacloon townland. Samuel Lewis's Topographical Dictionary of Ireland (1837) also notes it as a gentleman's seat. The Townland Valuation of 1828–40 lists a house in Lisnacloon townland as the dwelling of Sir Robert Ferguson and values it at £12 14s 10d, with dimensions given for a house with three additions and outbuildings, though it is not certain this refers to the present building. Griffith's Valuation of 1856–64 records the house as the residence of James Anderson Esq, leased from Sir Robert Ferguson Baronet, and valued at £21, later amended to £25. A gate lodge is also listed at £1, leased from James Anderson. By 1862 the house had become a rectory occupied by the Reverend M. C. Motherwell, leased from William Knox and valued at £30. It subsequently passed through many occupants corresponding to successive incumbents of Termonamongan parish. In 1927 the Reverend Robert Matchitt leased the house from the Trustees of the Church at a valuation of £20. The 1899 valuers' notes include a plan and dimensions for the house, outbuildings, and gate lodge.
