A house built on linen thread
The money that raised Gilford Castle came from sewing thread. It was built in the 1860s for Benjamin Dickson, a partner in Dunbar McMaster, the linen-thread firm whose mill had turned Gilford from a river-ford hamlet into a Victorian mill town. Dickson bought the old demesne after the Johnston baronetcy died out in 1841, cleared away the decaying earlier castle, and commissioned a new one from the Glasgow architect William Spence. Completed around 1870, it is Scots Baronial to the core: grey stone above the water, a corner turret, tall bay windows and balustraded parapets.
The village grew around the mill, not the house. Rows of red-brick workers’ houses still line the streets below, and the Dunbar McMaster works ran until 1986. When it closed, Gilford quietened. The castle, set back in its wooded grounds, stayed in the same family for more than a century.

Can you actually visit?
Here is the honest part: Gilford Castle is a private house, not a visitor attraction. There is no ticket office, no set opening hours and no public tour. You cannot wander the demesne or knock at the door. What the current owners run instead is an exclusive-use operation, the whole castle and estate taken by a single party for a stay or an event, arranged by consultation rather than by turning up. Planning permission has been granted to convert it into a guesthouse with a conference centre, and the estate has said it opens to enquiries from 2026, so access may loosen. For now, treat it as a place to book, not a place to drop in on.
From the public road and the village you can see the castle rising above the Bann through the trees. For a casual visitor, that is as close as it gets.
The estate, the river and the horses
Behind the gates sit more than 200 acres. The River Bann runs right through the grounds and carries the estate’s fishing, and guests can canoe a stretch of it. There are ornamental gardens, old woodland walks, and a serious equestrian yard: a dozen stables, a floodlit sand-and-fibre arena, and gallops laid to sand across the grazing fields. A three-bedroom cottage, a gate lodge and a courtyard apartment are dotted about the demesne.

The estate has changed hands rarely. When it was offered for sale recently, the first time on the open market in over a hundred years, the guide price ran to around £2.3 million, which tells you the scale of what is behind the wall.
Nearby
Gilford sits on the Bann between Banbridge and Portadown. Banbridge, five minutes down the road, has the deep road cutting known as the Cut and the F.E. McWilliam Gallery, devoted to the locally born sculptor. The Game of Thrones Studio Tour sits on the town’s edge at the old Linen Mill studios. West along the line of the canal, Scarva stages its Sham Fight every 13 July.
If you want to see inside Gilford Castle rather than glimpse it from the road, the only route is to contact the estate directly and book it, for a stay or an event. Anyone hoping to walk the grounds for free on a Sunday afternoon will be turned back at the gate.
