Place & story

Castlehill House and John Walshe

Castlehill House was being rebuilt for John Walshe in 1838. Its origins may extend back to an eighteenth-century house associated with the McCormick family, but the surviving form principally records nineteenth-century work. A central projection and carefully detailed entrance organise its symmetrical front. Doric columns frame the door beneath a fanlight, while sash windows, interior joinery and plasterwork preserve much of the recorded historic fabric. A walled garden and estate outbuildings contribute to the setting overlooking Lough Conn. [2]

Two houses within Enniscoe

Nearby Enniscoe has an unusually clear sequence of enlargement. George Jackson built its older, narrow house in the 1740s or 1750s; his son, also George, added the larger Georgian front in the 1790s. The earlier building survives inside the later one. The enlargement was structurally complete by 1798, when the house sustained damage during the French invasion and rebellion. Its reception rooms and oval stair landing belong to that later transformation of the family home. [3]

People & connections

The garden’s later history

Madeleine Jackson inherited Enniscoe in the 1830s. With her husband Mervyn Pratt she repaired the house and developed gardens within the existing walls. Their descendants continued that work, including another Mervyn Pratt, who concentrated on the garden until his death in 1950. The surviving grounds include a Victorian walled garden, an organic garden and pleasure grounds extending towards Lough Conn. Restoration under the Great Gardens of Ireland programme helped preserve these designed spaces as part of the estate’s historical character. [3] [4]
