The Hill Radnor is a native hill or mountain breed most commonly found in the Border counties running from the North of Powys down to South West Herefordshire and Monmouthshire. It is a heavy breed which has good body length and width in its hind quarters, standing on well set legs with an abundance of bone.

The Hill Radnor is a healthy breed free from many of the contagious and hereditary diseases which often affect other breeds.

The Hill Radnor sheep produces a dense white fleece which is popular with the trade and also much used by local spinners and weavers, with whom it is in great demand with an average weight from 2-2½kgs. The wool is retained up until shearing and is not shed around as with some hill breeds. In competitions the Radnor fleece has done exceedingly well.

The Radnor ewes when mated with Down Rams produce progeny which are early maturing. The Radnor rams are frequently used on other breeds of hill ewes to improve weight gain, size and confirmation without losing the hardiness so vital in a hill environment. The carcass produced by the Hill Radnor is very popular with butchers and housewives alike and much sought-after. Radnor carcasses have done extremely well at the Welsh Winter Fair and also at The Royal Smithfield Show, where they have won the hill breed championship on numerous occasions.

In 1993 the Hill Radnor was registered with the Rare Breeds Society. Since that time the membership has grown and new members have joined the Society from much further afield. The breed has proved to be a popular with many breeders as the sheep have a docile temperament, an attractive appearance and can, if required, be used for crossing with other breeds.
