Located roughly 25 metres south of a small stream, this intriguing historical feature appeared on old Ordnance Survey 25-inch maps as a rectangular area measuring approximately 24 metres northwest to southeast and 20 metres northeast to southwest. The site was enclosed by a substantial earthen bank, estimated at about 15 metres wide, which would have formed an impressive boundary around the central area.

Unfortunately, by 1972, any visible traces of this potentially significant medieval site had been completely obliterated. According to records held in the Sites and Monuments Record file, the area had been recently bulldozed at that time, erasing centuries of history from the landscape. Before its destruction, the broad enclosing bank and rectangular layout strongly suggested this was a moated site; a type of medieval settlement typically associated with Anglo-Norman colonisation in Ireland during the 13th and 14th centuries.

Moated sites like this possible example at Gilbinstown were essentially fortified farmsteads, usually consisting of a rectangular platform surrounded by a water-filled ditch or moat, with the excavated earth piled up to form the enclosing bank. These sites served both defensive and status purposes, protecting their inhabitants whilst also demonstrating their social standing in medieval Irish society. Though this particular site has been lost to modern agricultural improvements, its documentation helps preserve knowledge of Kildare's rich medieval heritage and the patterns of settlement that once dotted the Irish countryside.
