What remains of Fennor Castle, County Meath. Situated on ground above the Boyne, the building looks north across the river to Slane village. It was constructed in two phases: that section closest to the Boyne looks to have been a tower house, perhaps dating from the 15th or early 16th century. A three-storey, six-bayed gable-ended house was added to the south-side of the earlier structure, perhaps in the late 16th or 17th century when the tower house may have been adapted to accommodate a staircase. There appears to be little information about the castle’s history: it was already a ruin when drawn by George Victor du Noyer in the mid-19th century.
