It appears first in the official English records in 1210 when King John laid siege to it and took control of what was then Ulster's premier strategic garrison. Following its capture, constables were appointed to command the castle and the surrounding area. In 1217 the new constable, De Serlane, was assigned one hundred pounds to build a new curtain wall so that the approach along the rock could be protected, as well as the eastern approaches over the sand exposed at low tide. The middle-ward curtain wall was later reduced to ground level in the eighteenth century, save along the seaward side, where it survives with a postern gate and the east tower, notable for a fine array of cross-bow loops at basement level. A chamber on the first floor of the east tower is believed to have been the castle's chapel on account of its fine Romanesque-style double window surround, though the original chapel must have been in the inner ward. The ribbed vault over the entrance passage, the murder hole and the massive portcullis at either end of the gatehouse are later insertions started by Hugh de Lacey who died in 1248 and did not live to see its completion in around 1250. It was finished by King Henry III. After the collapse of the Earldom of Ulster in 1333, the castle remained the Crown's principal residential and administrative centre in the north of Ireland. During the early stages of the Nine Years War (1595–1603), when English influence in the north became tenuous, crown forces were supplied and maintained through the town's port. And in 1597, the surrounding country was the scene for the Battle of Carrickfergus. During the sixteenth and seventeenth centuries improvements were made to accommodate artillery, including externally splayed gunports and embrasures for cannon, though these improvements did not prevent the castle from being attacked and captured on many occasions during this time. Marshal Schomberg besieged and took the castle in the week-long Siege of Carrickfergus in 1689. This is also the place where Schomberg's leader, King William III first set foot in Ireland on 14 June 1690. In 1760, after fierce fighting in the town, it was surrendered to French invaders under the command of Francois Thurot. They looted the castle and town and then left, only to be caught by the Royal Navy.
