The History of Trim and the Porchfield

The foundation of the town of Trim dates back to the 5th Century AD but excavations of an area to the south of the Castle revealed that there may have been settlers in the region from as early as 370-BC. It is, however, the medieval history of Trim that has had the most significant impact on shaping the town that you are visiting today. As you walk through the Porchfield, you will see some fantastic examples of Trim’s medieval heritage in some of the structures that still remain in the area.

Along with the historical monuments that are visible at every turn, the River Boyne also plays a starring role in this landscape. The name Trim comes from the Irish Áth Truim meaning 'the ford of the elder trees'. A ford being a shallow place for crossing a river.

While the location of the river encouraged the first inhabitants of this area to settle here, it is now greatly valued as fantastic resource for outdoor recreation and is the location of one of the world’s first accredited Blueways, awarded in 2022.
