Trim, also called King John’s Castle, recently restored as a “preserved ruin,” is the most massive and important Anglo-Norman castle in Ireland. It proved all but impregnable for over 4 centuries (late 12th to mid-17th), suffering
only one siege during that entire period. In fact, until it collapsed sometime in the 17th century, it never underwent any significant alteration. For anyone with imagination, Trim is a virtual gateway into medieval Ireland.
