ASHLEIGH HOUSE, Maghera, County Down, is a Georgian two storey, late Regency style gentleman’s residence of ca 1840, set at the end of a winding drive to the north of the Bryansford Road, approximately half a mile north-west of Newcastle.

The main building is roughly square in plan, with a projecting porch to the front and a long narrow wing to the north which links to outbuildings.

The front façade is symmetrical.


In the centre of the ground floor is a large projecting porch set with a slightly projecting bay.

Granite steps lead to a broad timber panelled door to the west front of the porch, a fanlight above with chamfered top corners and margin panes.

The rear elevation of the this north wing appears to have some large modern windows, but the main hipped roof section of the house appears largely original.

There are original outbuildings to the north.

The house was built by the Rev William Randal Slacke, Rector of St John's, Newcastle.

He lived in the house until his death in 1877.

His widow lived in it during the 1880s, and then her son, Colonel William Randal Slacke, lived in it occasionally until at least 1918.

The house appears to have been rented to others for certain years during this period (e.g. 1861-65 & 1907-10), when William Slacke lived in the rectory, and his son was serving elsewhere.

The elder son, the Rev Owen Randal Slacke, was Rector of Bryansford, 1919-28.

I wish to express my gratitude to History of Newcastle for their assistance with this article.
