This intriguing structure appears on Newcomen’s map from 1657, marking its presence in the landscape during the mid-17th century. The building’s multiple names hint at its varied uses over time; a tholsel typically served as a toll house or meeting place for merchants and civic officials, whilst the rather inviting moniker ‘Castle of Comfort’ suggests it may have offered hospitality or refuge to travellers crossing between County Meath and County Louth.

The site’s history is documented in D’Alton’s work from 1844, which provides valuable insights into this now-vanished structure. Located in Lagavooren, County Louth, the building would have commanded an important position near the river crossing, perfectly placed to monitor and control movement along this significant waterway. The Boyne has long served as both a boundary and a thoroughfare in Irish history, making any fortified structure along its banks strategically valuable.

Today, no visible traces remain above ground of this once-prominent building. Like many Irish tower houses and fortifications, it has succumbed to time, weather, and human activity, leaving only documentary evidence and historical maps to tell its story. The site was formally recorded in both the Archaeological Inventory of County Louth (1986) and the Archaeological Survey of County Louth (1991), ensuring that whilst the physical structure has disappeared, its place in the historical landscape of the Boyne Valley remains preserved in the archaeological record.
