[4] Along with Eddisbury and Oakmere, Kelsborrow forms a small cluster of Iron Age hill forts within 3 miles (5 km) of each other, near the Mouldsworth Gap, a break in the central ridge that runs north–south through Cheshire.

[2] Multivallate (more than one series of earthworks) forts are common in southern England; that Kelsborrow Castle is single vallate (i.e. it has only one ditch and bank) means it is probably a one-phase site, indicating it would only have been used for a short time.

[8] Geophysical surveys and small-scale archaeological excavations in 1973 and 1996 indicated that there may be structures such as storage pits buried within the hill fort.

The site is part of wider agricultural land and suffers erosion from vehicles and livestock movement.

[9] Five of the hill forts in Cheshire have been assessed as being "at high risk" compared to 15% of North West England's Scheduled Monuments.
