Historical Context
Trim Castle rose beside a strategic ford of the Boyne after 1172, when Hugh de Lacy—granted Meath by Henry II—founded a timber fortress to anchor Norman control. Burned in 1174 by High King Ruaidrí Ua Conchobair, it was rebuilt in stone; by the early 1200s Walter de Lacy completed the extraordinary multi-sided, cruciform keep and powerful curtain walls. As the caput of the Lordship of Meath and a bulwark on the edge of the Pale, Trim hosted royal visitors such as King John and Richard II, convened sessions of the Irish Parliament, and even operated a mint. Refortified during the 17th-century wars, it later declined until the Irish state acquired it in 1993. Meticulous conservation followed, and the castle reopened to the public in 2000.
