Brockagh Castle situated on a low natural hill which forms part of a long N-S ridge, in undulating grassland, with good views in all directions. Rectangular building aligned NE-SW depicted as an upstanding structure on 1837 ed. OS 6-inch map. On the revised 1911 ed. OS 25-inch map only the SW gable is shown as standing in the centre of sub-circular shaped enclosure (CUCAP BGH102) which is not depicted on the 1837 ed. OS 6-inch map. The ruins of a rectangular structure (approx. dims. 11m E-W x 7m N-S) aligned on a NE-SW axis built of roughly dressed mortared limestone, with a slight base batter standing in the centre of a sub-circular shaped enclosure (WM012-173001-). Only the SW wall survives upstanding (approx. H 3m) and has a single window in the centre of the wall. Elsewhere the outline of the castle is visible as low grass covered wall footings. The corners of the castle are rounded in a similar fashion to Carrick Castle (WM011-012----). The terrier of the 1655-9 Down Survey map of Mullingar parish listed Andrew Tuite as the owner of the lands of Brockagh in 1641 (NLI, MS 723-4).
