What is recorded here

Carrickfergus Castle is the best preserved medieval structure in Northern Ireland, standing on a rocky promontory where the sea still touches three sides of its ancient walls. John de Courcy built it in 1177 as his headquarters after conquering eastern Ulster, creating a fortress that commanded the bay and the developing town beneath its shadow. Scottish, Irish, English and French forces besieged it repeatedly because holding the castle meant holding the northern coast. The stone gatehouse, murder hole and cross-bow loops remain visible, testifying to seven centuries of danger and defiance.
