On the low-lying ground along the eastern shore of Lough Forbes in County Longford stands what remains of a once-significant structure that has puzzled historians and archaeologists alike.
Site of Castle, Castleforbes Demesne, Co. Longford
Early cartographic evidence provides tantalising glimpses of what this site once looked like; a 17th-century map of Longford barony shows it as a castellated tower, whilst the Down Survey maps from 1655-6 depict something rather more elaborate. These historical documents show a two-storey central block flanked by gable-fronted towers at each end, complete with a central ground-floor doorway, two first-floor windows, and a prominent chimney stack that rose well above the roofline.
Today, visitors to the site will find something far less grand but equally intriguing. What remains is an irregular mound of stone and earth stretching roughly 52 metres north to south and 24 metres east to west, bounded on its eastern side by a low scarp. The interior contains a disturbed rectangular area, open to the north and south but enclosed by broad, irregular banks of stone and earth on the east and west sides. The surface is dotted with depressions and hummocks, and whilst considerable stone is visible throughout, no clear structural patterns can be traced. Some larger stones to the north appear to have been dumped there at a later date, perhaps during agricultural clearance.
The site poses an interesting historical puzzle; it may have begun life as a medieval castle that was later incorporated into a late 16th or early 17th-century house, or it could date entirely from the later period. The transformation from the substantial building shown in historical maps to today’s earthwork remains speaks to the dramatic changes that have swept through this part of Longford over the centuries. Whether medieval fortress, early modern manor house, or a combination of both, this enigmatic site continues to guard its secrets amongst the quiet shores of Lough Forbes.
