What survives today are two crumbling walls of what was once a tower house, built from uncoursed limestone rubble; a common construction method for defensive structures in medieval Ireland. The eastern wall stretches 8.5 metres north to south and rises to an internal height of 2 metres, whilst the southern wall runs 4 metres east to west. These fragments suggest the main tower stood on the eastern side of the mound, with the bawn, a fortified courtyard typical of Irish tower houses, extending westward.

The castle’s position on this modest elevation would have provided some defensive advantage in the marshy landscape, allowing its inhabitants to survey the surrounding countryside whilst keeping their feet relatively dry. A church sits to the southeast, hinting at the settlement pattern common in medieval Ireland where ecclesiastical and secular power centres often developed in close proximity. The mound itself is defined by several irregular earthworks, possibly the remains of defensive ditches or earlier occupation layers that have been weathered and reshaped by centuries of agricultural activity.

By the time the Ordnance Survey mapped the area in the 19th century, Bracklin Castle had already diminished to a small square building on their six-inch maps, suggesting it may have been partially intact or repurposed at that time. Today, these lonely walls stand as subtle markers of the area’s medieval past, easily overlooked amongst the fields but representing the kind of minor lordship that once controlled much of rural Ireland.
