Trim Castle is the largest Anglo-Norman castle in Ireland, constructed over a thirty-year period starting in 1176. The site is dominated by a massive three-story keep, a 20-sided cruciform tower that served as a central defensive strongpoint. The castle was built by Hugh de Lacy and his son, Walter, on land granted by King Henry II. It functions as a classic example of an enclosure castle, featuring curtain walls and gatehouses that protected the inner ward. The structure underwent significant restoration to preserve its limestone masonry. It occupies a strategic position overlooking the River Boyne. The castle's architecture reflects the transition from wooden fortifications to stone keeps during the late 12th century.
