Carrickfergus Castle History

Who built Carrickfergus castle?

Carrickfergus history begins when the Castle was built by John de Courcy in 1177 and used as his headquarters until around 1204 when Courcy lost the castle to Hugh de Lacy. The original castle included a bailey, with an inner wall and a great hall with a curtain wall built around the exterior to protect the castle from the sea.

John de Courcy was married to Affreca de Courcy or Affrica Guðrøðardóttir a late 12th-century noblewoman.

Affreca is noted for religious patronage in Northern Ireland and founded Grey Abbey, on the Ards peninsula. A statue of her sits on a high wall in Carrickfergus with a plaque that says “thinking of home”.

John de Courcy built the castle and ruled as a petty King because Richard the Lionheart simply didn’t give a toss about Ireland in fact he barely cared about being King of England either.

When Richard died in 1199 his brother John became King of England and he did care about Ireland and felt that John de Courcy had usurped and set up his own kingdom.  John commissioned Hugh de Lacy a Norman Lord living south of Dublin to bring de Courcy to heel.

John de Courcy came under attack by King John’s soldiers led by Hugh de Lacy and lost the castle. In 1210 and in 2017 de Lacy added a larger castle curtain wall to protect the eastern side and a massive portcullis at the gatehouse and a vault all of which were finished in 1250.

John de Courcy later tried to reclaim the Castle but was unsuccessful and was sentenced to life in prison. King John later released him to go on a pilgrimage to the Holy Land.  The King also ordered de Lacy to hand the castle over to the crown which he refused to do.

King John then laid siege to the Castle and eventually de Lacy surrendered it to the crown where for the next 700 years Carrickfergus would remain a military installation.

One of the most notorious men in Ireland was Arthur Chichester who was appointed Governor of Carrickfergus on the death of his brother, John in 1598 who was killed at the Battle of Carrickfergus. The stories say that John was decapitated and his head used as a football by James Sorley boy MacDonnell who commanded the opposing forces at the battle. Sorley Boy was poisoned at Dunluce Castle later on the orders of Robert Cecil, Privy Council to Queen Elizabeth II) to placate Chichester.

Chichester was a much-hated man due to his persecution of Catholics in Ireland and his belief that they were a threat to the Crown. A major figure in the Plantation of Ulster after the Flight of the Earls in Donegal he was responsible for all the native lords of Ireland loss of lands.

Over the years the Castle was attacked and taken many times. In 1690 it was taken in the name of King William III and in 1760 by Francois Thurot took the Castle for the French.

Having been reconstructed three times, Carrickfergus Castle endures to this day, preserving six of the original 22 cannons that once defended its sea-facing walls. Over the years, it served various purposes, including as an armoury and garrison during World War I, and later as an air-raid shelter in World War II.

Carrickfergus and pirates

Thurot was a privateer (pirate) and he preyed on British ships he spent a year in an English prison before being released at which time he became a captain of his own vessel. Thurot’s grandfather was Irish and he held Irish sympathies and spent years smuggling between Ireland and England. When his ship was seized by the British and impounded the British refused to give it back to him. Thurot went to the French navy and obtained a ship and led a squadron of ships that harried the British from 1756 to 1760.

In 1760 he landed at Carrickfergus, capturing the castle in what became known as the second Battle of Carrickfergus and commandeering supplies from the local people. He was not the last pirate to menace the castle, however. In 1776 during the revolutionary war in America, the American privateer John Paul Jones was leading lighting raids on the British coastline. One of his targets was moored at Carrickfergus – the HMS Drake.

Jones attacked at night but the sailor who dropped the anchor was drunk and got the timing wrong. Fleeing the coast the Drake pursued and attacked Jones. Jones won the find and captured the ship. Over time Jones captured 11 British ships, 8 of which he sent back to Boston to be sold for a total of over a million dollars to help fund the war.

Button Cap Carrickfergus – the Ghost

One of the most prominent legends about ghosts in Castles in Ireland is that of  ‘Button Cap’, a young soldier who was stationed at Carrickfergus during the late 18th century.

The legend of Button Cap is that of mistaken identity. Robert Rainey, a fellow soldier found out that his fiancee had been cheating on him with a man named Jennings, who was attacked and killed by Rainey. But it turns out that he had mistaken Jennings for a man called Timothy Lavery. He attacked the man in the night and dealt him a fatal blow before fleeing. Jennings lived long enough to tell the story and he swore to haunt the castle forever.
