Military Buildings
On the western bank of the River Easky estuary in County Sligo, a low, split-level ruin sits on a rock outcrop and juts out slightly over the water.
What makes it immediately curious is its arrangement: a smaller, lower room projects 1.7 metres over the estuary and is fitted with a single gun port and nine musket loops, openings designed to allow defenders to fire weapons while remaining largely protected behind thick stone walls. This is not a grand tower house or a gentleman's residence but something more purposeful and compact, built to watch and, if necessary, to shoot.
The structure is thought to date from the seventeenth century, placing it in the turbulent post-medieval period when control of waterways and estuaries in the west of Ireland carried real strategic weight. The building is subrectangular in plan, single-storey but arranged across two levels that are separated by a cross-wall. The lower, weapon-fitted room gives way to a larger upper room, which survives without features, and beyond that a third rectangular room, now largely choked with collapsed masonry. Around the northern and western sides of the structure runs a low, curving bank of earth and stone, between roughly a metre and just under four metres wide and still faintly visible on the ground. This is almost certainly the remnant of a bawn wall, the kind of defensive enclosure, typically of mortared stone, that was commonly built around fortified houses and smaller garrison buildings of the period to protect the surrounding yard and its occupants.
The site sits close to the shoreline and the low earthen bank is easy to miss, but the musket loops in the projecting lower room are visible enough to give a clear sense of what this place once was: a small, deliberate fortification positioned to command the mouth of the Easky, watching whatever came in from the sea.
