The internal buildings are gone entirely, burnt in 1922 and then demolished around the 1940s, yet the enclosing walls still stand on three sides, and those walls have something to say. Set into each of the surviving limestone faces is a central angled projection, roughly three metres wide and three metres deep, fitted with gun loops. These were not decorative features; they allowed defenders to direct fire along the outer face of the wall rather than simply through it, a design detail that places this modest provincial garrison in a longer tradition of defensive military architecture.

By 1837, the topographer Samuel Lewis described the complex in matter-of-fact terms as a neat range of buildings capable of housing three officers and seventy-two non-commissioned officers and privates. The 1842 Ordnance Survey six-inch map labels it plainly as Infantry Barracks and shows a rectangular enclosure of roughly seventy metres north to south and fifty metres east to west, with a large U-shaped building and a scattering of smaller structures occupying the southern half of the compound. The perimeter had piered entrances, one on the west side and one on the north, both of which are now blocked. The buildings inside vanished after the burning during the Civil War period, but their presence persists as ghostly outlines still visible in the plaster on the internal face of the western wall, alongside corbels, small stone brackets projecting from the interior of the eastern wall, which once supported floors or roof timbers.

The site sits on the western side of the road on the south-west approach to Mitchelstown. What a visitor encounters today is essentially a walled enclosure without its contents, the limestone rubble perimeter carrying the memory of a structure that was functional rather than grand, provincial rather than strategic, and which met its end in a very Irish way.
