Pant Mawr Rabbit Farm, Ystradfellte, comprises a 1,714 acre tract of moorland, enclosed within 'a strong drystone wall', with at least 80 pillow mounds unevenly distributed over it. Also within the enclosure are isolated drystone-walled pits, possibly rabbit traps, possible breeding pens, pits in close proximity to the pillow mounds, and five ungated fields (Archaeology in Wales 2 (1969), 34-5).

(The summary descriptions following are divided into four sections by OS quarter sheets):

SN81SE:
That part of the site which lies in SN81SE is mostly forested, bounded by a stone wall; the features which survive have been left in clearings or not yet located in the forest but there may have been many more features which have been destroyed. Remains include substantial pillow mounds, pit traps, walled enclosures and a warrener's cottage, Blaen-cwm.
