Site of Old Castle, Coolnashinny, Co. Cavan
During the reign of Charles II, between 1660 and 1685, Dame Mary Craig maintained a house here with two hearths, as recorded in the Hearth Money Rolls. The site, marked on Ordnance Survey maps from 1835 onwards, consists of a roughly rectangular area measuring about 55 metres east to west and 50 metres north to south, its boundaries still visible today through old field banks, including what appears to be a double bank on the eastern side.
The most striking feature that survives is a circular tower at the southwest corner of what was once the bawn enclosure. This two-storey structure, built from rubble masonry with an internal diameter of 2.8 metres, has its doorway oriented northeast towards the former courtyard and features simple rectangular slit windows. The tower appears to have been repurposed, possibly as a mausoleum, with a corbelled roof added over the ground floor; a fascinating example of how these defensive structures found new uses long after their military purpose had passed.
An intriguing connection to the site’s later history comes in the form of a 19th-century headstone that once stood within the tower but has since been moved to Croghan House, about 130 metres to the north. The memorial commemorates Reverend George Carson and his wife Mary, with Carson likely having served at the Presbyterian church in nearby Croaghan, some 270 metres away. The inscription, carved in both cursive and roman lettering, speaks of Carson as a champion of Christian liberty, “wishing for the Resurrection of the Just”, though time has rendered parts of the text illegible. This layering of history; from medieval stronghold to religious monument; makes the site a compelling example of how Irish landscapes carry multiple stories within their stones.
