Fairy fort / earthen ringfort in Ballinderry (clonlonan By.)

Situated in undulating pasture. Depicted on the 1837 ed. OS 6-inch map as a large subcircular-shaped earthwork (overall dims. 65m E-W; 59m N-S). Not depicted on the revised 1910 ed. OS 25-inch map, on this map the area is partially occupied by an irregular-shaped grove of trees on Ballinderry estate. Monument is visible today as a subcircular-shaped cropmark on Digital Globe aerial photography. Probable ringfort that was reused as a landscape feature in the post 1700 period.
