The site, located in the townland of Carrick, appears on the 1837 Ordnance Survey map as a rectangular building on what was then a small island called Inchacrone, sitting about 180 metres west of the shoreline. When the antiquarian John O’Donovan visited that same year, he noted that the island was planted with trees and scattered with the ruins of what appeared to be a house or castle.

The island’s transformation into a promontory is a story of Victorian engineering and environmental change. Following drainage schemes on the River Brosna, the water level of Lough Ennell dropped significantly, connecting the former island permanently to the mainland. By 1981, surveyors could find no trace of the castle ruins that O’Donovan had documented; the stones had completely disappeared. The area has since been thoroughly transformed, with modern houses, landscaped gardens, and a public road now occupying the space where medieval walls once stood.

Today, aerial photography shows the site as a small, wooded promontory with three buildings and no visible remnants of its medieval past. The castle that once commanded views across Lough Ennell has been erased not just by time, but by the very reshaping of the landscape itself; first by water drainage that changed an island into a peninsula, then by modern development that swept away the last physical traces of this forgotten stronghold.
