Overview
Jonathan Swift spent a lonely eighteen months at Kilroot in the 1690s as its parish prebend, and the shoreline he’d have walked is now framed by a power station and by salt mines that run for miles out under the Lough. That collision – an early Christian church site pressed up against heavy industry – is the whole character of the place. Kilroot (Irish: Cill Ruaidh) sits just east of Carrickfergus on the northern shore of Belfast Lough, reached via Fort Road off the A2 Larne road. The name means ‘church of the red’, most likely after the red-brown Mercia Mudstone in the local soil rather than any building.
Be clear about what it is: a modest graveyard and a roofless house, set against a working plant and a fenced-off mine. It’s a short, curious detour if you’re already in Carrickfergus, not a destination in its own right.
History
Early Christian foundations
According to the Codex Salmanticensis, St Ailbhe of Emly sent his disciple Colmán mac Cathbaid to found a church here around 500 CE. A blessed stone was said to have produced a spring – the ‘Unfailing Stream of Cill-ruaidh’ – which still runs as an unlined spring just southwest of the present graveyard. The name stuck, marking the site as a place of worship long before the medieval parish system arrived.
Medieval and post-medieval
By the 13th century this was the parish church of St Colmán, with a bullaun stone – used for grinding or as a font – built into its wall. The church fell into ruin sometime after the 15th century, leaving foundations that still show on the 1857 Ordnance Survey map.
In the early 17th century Edward Brice, a Scottish minister, acquired the land and built the three-storey Kilroot House inside a bawn, a walled defensive enclosure. Two ruined bastions and about a third of the bawn wall survive today. The house later became the prebendal residence of the Church of Ireland, and Jonathan Swift held that post from 1695 to 1696. He is said to have lived nearby in the ‘Round House’, a thatched oval cottage with no corners for the devil to hide in, demolished after a fire in 1959. Kilroot House itself was a ruin by the late 19th century; the interior is now closed off because of falling masonry.
Industrial era
The 20th century brought a very different landscape. Kilroot power station, coal-fired for decades before it switched to gas, once supplied roughly a third of Northern Ireland’s electricity. Beside it, a network of rock-salt mines stretches some 30 miles (48 km) beneath Kilroot, Eden and the Carrickfergus East Division, producing salt for road-gritting. The mines aren’t open to visitors, but their silhouette – stacks, conveyors, spoil – is now as much a part of Kilroot as the ruins.
What to see and do
Kilroot House and graveyard
The most atmospheric corner is the ruined house within its bawn, with the two broken bastions and the graveyard – locally ‘God’s Acre’ – alongside. A short, level path leads from a small lay-by on Fort Road to the entrance gate, so it’s easy to reach on foot. In 2002 a retaining wall collapsed here and the excavation that followed turned up burials and later deposits, confirming how long the ground has been in use.
Industrial views
The power station isn’t open for tours, but the jetty at its northern edge is publicly accessible and gives you the turbine stacks straight across the water. It’s an oddly good photograph: dressed stone graves in the foreground, industry behind.
Coastal walks
The shoreline makes a natural corridor for walkers and cyclists, with the path linking back toward Carrickfergus and its castle. It’s an easy way to stitch a short history stop onto a longer walk along the Lough. Waders and gulls work the tide line, and spring and autumn bring passage birds through.
Practical information
Access and parking – from the A2 Larne road, turn onto Fort Road and follow the signs toward Kilroot Business Park. A small lay-by on the left gives free parking. The site is unstaffed.
Opening hours and admission – the graveyard and ruins are open year-round and free. The jetty is accessible too, though security patrols can restrict it at times.
Accessibility – the graveyard path is fairly level, but the bawn walls are uneven and the interior of Kilroot House is closed on safety grounds. Firm shoes are sensible after rain.
Getting there – regular buses run from Carrickfergus and Belfast, and the nearest railway station is Carrickfergus, about 2 km north. By car, the A2 links directly to Belfast, roughly 20 km away.
Nearby amenities – Kilroot itself has little in the way of food, but Carrickfergus is minutes away, with cafés, pubs and restaurants clustered around the castle.
Safety – the jetty is slippery when wet, so mind the water’s edge, and the salt-mine ground is fenced and signed ‘No Entry’.
Time it for late afternoon to catch the light shifting over the Lough from the jetty, then drive the couple of kilometres into Carrickfergus for dinner by the castle.
