Carrickfergus Castle

Carrickfergus Castle: Ireland's Greatest Norman Fortress, Above Belfast Lough

In 1315, Robert the Bruce's brother Edward invaded Ireland with an army and besieged Carrickfergus Castle. The siege went on so long, and provisions ran so completely dry, that the garrison — before eventually surrendering — was reduced to eating the leather from their boots and equipment. The detail appears in contemporary chronicles and has attached itself to the castle ever since: a vivid measure of how seriously the defenders took their duty and how grimly effective a prolonged siege could be.

Carrickfergus Castle was built in 1177 by John de Courcy, an Anglo-Norman knight who had just conquered eastern Ulster and needed a headquarters. He chose a rocky outcrop on the northern shore of Belfast Lough where the sea provided natural defences on three sides. The castle he built — and which subsequent lords expanded over the following 65 years — is one of the best-preserved medieval fortresses in Ireland, its great square keep and curtain walls standing largely as they were in the 13th century.

In 1690, King William III of Orange came ashore at Carrickfergus on his way to the Battle of the Boyne. In 1760, a French privateer briefly seized it. In 1778, John Paul Jones fought a naval engagement in the waters just offshore. It served as a prison during the Napoleonic Wars, a garrison in World War One and an air-raid shelter in World War Two. Important: the castle is closed on Mondays (except bank holidays) throughout the year. This guide covers everything you need to plan your visit.

Where Is Carrickfergus Castle?

Carrickfergus Castle is at Marine Highway, Carrickfergus, County Antrim, on the northern shore of Belfast Lough, approximately 10 miles north of Belfast city centre. By car from Belfast, take the M5 motorway; the journey takes around 20 minutes. Free parking is available on site.

A Brief History of Carrickfergus Castle

John de Courcy built the Inner Ward and Great Tower from 1177, creating a powerful base for the Norman conquest of eastern Ulster. The castle was extended in phases: the Middle Ward was added in 1216, the Outer Ward between 1226 and 1242, giving the castle its present three-part structure. The strategic position — water on three sides, with the lough as both moat and highway — made it the most significant fortress in Ulster for several centuries.

King John besieged and took the castle in 1210 from Hugh de Lacy, asserting English royal control. A century later, Edward Bruce's 1315 siege is the most famous episode — the garrison's leather-eating endurance before surrender became one of the defining stories in Ulster medieval history. The castle changed hands repeatedly across the centuries of Irish-English conflict.

The 17th and 18th centuries brought some of the most colourful chapters. In 1690, King William III — William of Orange — landed at Carrickfergus in June, just before crossing to the Boyne. One of the defining moments in Irish Protestant history had its staging post at this castle.

In 1760, during the Seven Years' War, the French privateer François Thurot led a raid on the town, briefly seized the castle and occupied it for a few days before withdrawing; he was caught and killed by the Royal Navy shortly after. In 1778, during the American War of Independence, John Paul Jones — the American naval hero — brought his ship into the North Channel and engaged the Royal Navy frigate HMS Drake in battle just offshore. The castle garrison watched from the walls.

The remarkable thing about Carrickfergus is the sheer accumulation of history on one site across eight centuries: Norman conquest, English royal assertion, Scottish invasion, Jacobite crisis, French privateering, American revolutionary naval engagement, Napoleonic imprisonment, two World Wars. Few buildings anywhere in Ireland have been more continuously and more consequentially used.

Architecture & Design

Carrickfergus Castle is a textbook example of Norman military architecture developing from simple keep to complex defensive system across three building phases. The Great Tower — a four-storey square keep — is the oldest and most imposing element, built by de Courcy in the Inner Ward and offering panoramic views of Belfast Lough from its battlements. The keep's walls are enormously thick, designed to resist both assault and artillery.

The gatehouse and barbican of the Outer Ward retain their murder holes and arrow slits. Six of the original 22 cannons from the 17th to 19th centuries survive and are displayed along the east battery, a tangible reminder of the castle's continued military role well beyond the medieval period. The curtain walls originally stood with water on three sides — land reclamation has reduced this, but the lough still forms the northern boundary, giving the castle its characteristic silhouette from the waterfront.

The Great Hall has been renovated with a new roof, restoring the main ceremonial space to something approaching its original function as a gathering place.

Legends & Lore

Carrickfergus Castle is not primarily known for ghost stories or folklore — its well-documented military and royal history is dramatic enough to sustain any number of visits without invention. The stories of Courcy's conquest, John's siege, Edward Bruce's leather-eating garrison, William's landing, Thurot's raid and John Paul Jones's naval engagement are not legend but documented history.

The castle's most enduring cultural connection is the traditional Irish folk song "Carrickfergus" — a song of longing and exile, with the castle and lough as its central image. Widely interpreted as a composition of the 18th or 19th century, it became one of the best-known Irish songs in the world through performances by Van Morrison, The Chieftains and countless others. The castle itself is named in the song's opening lines.

Carrickfergus also appeared as a filming location for Game of Thrones, adding a further layer of modern cultural recognition.

Conclusion

Carrickfergus Castle has been besieged by the English, by the Scots, by the French and by a garrison so hungry it ate its own leather. King William III landed at its feet in 1690. John Paul Jones fought a naval battle within sight of its walls in 1778.

François Thurot seized it for four days in 1760. A famous folk song carries its name around the world. And it is 10 miles and 20 minutes by train from Belfast, intact, open and still standing above Belfast Lough exactly where John de Courcy built it in 1177. Go on a Tuesday.
