Overview
The Anglo-Norman knight John de Courcy built Carrickfergus Castle in 1177 to control Belfast Lough, and most of what he raised is still standing – which makes it the best-preserved Norman castle in Ireland and the one thing to see here if you see nothing else. The town sits on the north shore of Belfast Lough, 12 miles northeast of Belfast, and counted a population of 28,141 at the 2021 census. The Irish name, Carraig Fhearghais (‘Fergus’ rock’), gives the place its origin story and its folk song. For most visitors it works as the first stop on the Causeway Coastal Route north, with the castle, the museum and the marina all within a few minutes’ walk of one another.
History
Legend traces the name to a 5th-century king, Fergus Mór, whose ship is said to have run aground on the rock the castle now stands on. The reliable history starts in 1177, when de Courcy threw up the fortress as the administrative centre of the Earldom of Ulster.
Over the next eight centuries the castle changed hands again and again: from de Lacy to King John, from the Scottish forces of Edward de Bruce to French privateers in 1760. It held out through a siege in the Nine Years’ War (1597) and the Williamite wars, and in June 1690 William III landed here before marching south to the Boyne. After its fighting days it served as a prison, a Napoleonic-era ordnance store, a garrison in the First World War and an air-raid shelter in the Second, passing into civilian hands in 1928.
The town later turned to industry, with Kilroot fibres and Rothmans cigarettes, and Northern Ireland’s largest power station opened at Kilroot in 1981. These days it is largely a commuter base for Belfast.
What to see and do
If your time is short, give it to the castle and skip the rest. The four-storey Norman keep is the reason people come, and the daily guided tours are free with admission – worth timing your arrival around, because the guides carry the history the costume rooms and giant chess set can only hint at. Inside you’ll also find the banqueting hall, the armoury, historic cannon and a sensory room aimed at children.
The Carrickfergus Museum & Civic Centre covers 800 years of town history across multimedia exhibits, with a café and step-free entrance – a fair wet-weather hour if the castle has worn out the children.
The marina and the seafront Marine Gardens are the place for a walk rather than a destination in themselves: boats, a promenade, playgrounds and picnic spots, with summer boat hire at the marina. St Nicholas’ Church, the Church of Ireland building near the old market square, is a quiet stop with a Norman foundation behind its 19th-century fabric. Carrickfergus Golf Club is an 18-hole parkland course a short walk from the centre, with lough views and a clubhouse café.
For food and a pint, the choice runs from JD Wetherspoon’s Central Bar to Ownie’s Bar and the Italian Castello Italia, several with outdoor seating over the lough.
Guided tours
The Northern Ireland Tourist Guide Association runs a 2.5-hour Carrickfergus Town & Castle Tour for small groups of up to 20. A guide walks you through the castle, the line of the former town walls, the North Gate, the Irish Gate and the Governor’s Palace, with the stories of King Fergus, John de Courcy, Arthur Chichester, Jonathan Swift and William of Orange. Tours run all year and can be booked for private or public groups, with guides available in English, French, German, Italian, Spanish, Mandarin, Japanese, Portuguese, Russian and Cantonese among others. Wear sturdy shoes and bring a waterproof – the walk is fully exposed.
A small thing worth catching
The bells of St Nicholas’ Church ring nightly at 9pm, the old signal that once warned townspeople the gates were about to close. It carries well along the promenade after dark.
