What is recorded here

An artificial hollow in an elevated position within a tree plantation. This feature appears to be the remains of open cast mining, possibly medieval or 17th-century in date. According to the OS letters (1839), this feature 'is called by the inhabitants "Cromwell's Pit"; it is an apparently artificial hollow, and it is said that Cromwell, from this, besieged "the Garrison."' (O'Flanagan 1930, vol. 1, 44). When visited in 1993 the area had been subject to land disturbance and there was no visible trace of the hollow at ground level and no local knowledge of its location (Farrelly et al. 1993, vol. 1, 129).
