Moat, Louth Hall, Co. Louth
Standing on a low ridge near the western bank of the River Glyde in County Louth, this medieval motte and bailey fortification offers a glimpse into Ireland's Norman past.

The site consists of a circular earthen mound, roughly 29 by 37 metres at its base and rising between 4.5 and 6.8 metres high. At its summit, the mound narrows to about 19.7 by 17 metres. Surrounding the southern edge, you can still trace the remains of a defensive ditch, or fosse, approximately 5 metres wide, though it’s now partially filled in where a modern field boundary crosses it. The northern side may have had a similar ditch, but today only hints remain beneath a field wall built along its path.
To the west of the motte lies what remains of the bailey; a degraded enclosure measuring about 45 metres north to south and 30 metres east to west. This lower courtyard would have once housed the everyday activities of the castle’s inhabitants, from stables to workshops. The bailey’s boundaries are still visible as earthen scarps, particularly pronounced on the northern side where the ground drops away sharply. The motte itself shows signs of later interference; quarrying has left a metre-deep hollow on the north-northeast side of the summit, where stone or earth was presumably removed for building projects elsewhere.
Archaeological surveys suggest there may be more to this site than meets the eye. A possible souterrain, one of those mysterious underground passages found throughout Ireland, is thought to exist within the motte itself. These details come from archaeological inventories compiled in 1986 and 1991, with updates from more recent research. While time and farming have softened the fortress’s once-imposing profile, the earthworks still clearly mark where Norman settlers once sought to control this strategic position along the Glyde valley.
