Though never marked on any edition of the Ordnance Survey 6-inch map, this Neolithic monument commands views of the mountain peaks of northern Leitrim and Sligo to the south, whilst the hills of southwest Donegal rise to the west and northwest. The entire structure sits within a long, grass-covered oval cairn that stretches 40.5 metres east to west and 16 metres at its widest point, bounded by a kerb of around 30 visible stones, with likely more buried beneath centuries of earth.

At the heart of this monument lies a large oval court, measuring 12.2 metres long and 8 metres wide, accessed through a narrow entrance passage on the southern side. This passage, roughly 3.5 metres long, narrows from 1.5 metres at its outer end to just 0.7 metres where it opens into the court itself. From this central space, two main galleries extend in opposite directions; the eastern gallery stretches 7.5 metres and contains two chambers separated by jamb stones, whilst its western counterpart runs 7 metres with a similar two-chamber arrangement. Both galleries retain their entrance jambs and displaced lintels, with the eastern lintel measuring an impressive 2.4 metres long and 0.7 metres thick.

What makes Ballymunterhiggin particularly intriguing is the presence of three subsidiary chambers that open directly onto the central court. Two of these sit close together on the northern side, whilst the third occupies a position on the southern side, just west of the main entrance. These smaller chambers, positioned at right angles to the monument’s main axis, add complexity to what is already an elaborate burial structure. The entire tomb represents sophisticated Neolithic engineering, with carefully selected and positioned stones creating distinct spaces for ritual and burial. Despite millennia of weathering and some structural displacement, the monument remains remarkably intact, offering visitors a chance to explore one of Ireland’s more complete court tomb examples.
