South-east and to the rear of Kilkea Castle, County Kildare are the remains of a 13th century church, once associated – as was the main building – with the FitzGeralds, Earls of Kildare (and later Dukes of Leinster). Only the east gable and the remains of a chapel to the north survive, along with fragments of monuments to this once-mighty family. Inserted into a wall, for example, is a carving of a chained and collared animal, which might be a dog or perhaps a monkey which featured on the FitzGerald arms. Aforementioned arms can also be found on another stone. Kilkea Castle is today an hotel.
