RATHROBIN
OS 24:14:2 (373,92) 'Rathrobin Castle (in ruins)'
OD 300-400 22615,21634
Castle (site) Situated on high ground within the demesne of Rathrobin House affording good views of the surrounding countryside. The Down Survey barony map of Ballyboy shows a large tower and some cabins in this townland. In 1641 the castle was in the possession of Dermot Doogan who was transplanted to Galway 1653-4 (Loeber Survey 1988). In 1694 Nicholas Biddulph apparently built a house near the old castle. A 19th -century house stood on its site until c. 1920 when it was burnt down. Apart from a rectangular hood-moulding of late medieval date incorporated into the gable end of an outbuilding to NW of the ruins of the 19th century house there are no upstanding remains of the castle. This architectural feature may have been part of the earlier castle, or Biddulph's 17th century house. (Bence-Jones 1978,240)
