On the River Boyne, Trim is home to the largest Anglo-Norman Castle in Ireland, Medieval Trim Castle, which was built by Hugh de Lacy in 1173. Explore medieval sites such as the Yellow Steeple formerly a seven-story church, Sheep’s Gate which is the only surviving medieval gateway to the town, and the ruins of Newtown Cathedral and Abbey.

During the early 1700s, Jonathan Swift, author of Gulliver’s Travels, lived nearby at Lacacor, where he served as vicar to a small congregation.

Discover the rich history of the town in the Trim Visitor Centre.
