Fairy fort or earthen ringfort in Castlelost

In level pasture. Circular area (diam. c. 38m N-S; 42.5m E-W) defined by a poorly preserved earthen bank mainly reduced to a scarp enclosed by a deep fosse, earth and stone bank, outer fosse with slight remains of a second external bank only visible from W-N. On S side of the ringfort, the external bank is incorporated into a post-1700 field boundary running E-W. Possible causewayed entrance gap (Wth 2m) at SE. Depicted as a rectangular tree plantation, similar to a moated site on the 1837 ed. OS 6-inch map. On the revised 1910 ed. OS 6-inch map the monument is hachured as a large circular bivallate ringfort.
