This Commandery was founded by Roger, Earl of Clare, in 1173. In 1182, his widow, Maud, Countess of Clare, gave the Commandery of Carbrook to the Knights Hospitallers, endowing it with the advowsons of Great and Little Carbrook, and with additional income from more than half of the properties in those parishes. These gifts were confirmed by her son Richard de Clare, Earl of Hertford, and King John in 1199. From this time, Maud, Countess of Clare, was styled the foundress. In the Church there are 16 stalls for the use of a Prior and 15 knights.
Nothing now exists of the original buildings.
Some of the Sisters of the Order were placed in a hospital near the Parish Church of St John the Baptist. In 1180, King Henry II gave the Monastery at Buckland in Somerset to the Knights Hospitallers on the condition that all the Sisters of the Order should reside there, making Buckland became the only house in England for the Sisters of the Order. Even thought the Sisters of Carbrook Parva went to Buckland, the Parish was charged with an annual payment of 13s 4d towards their support. Nothing remains above the foundations. The Church of St John was pulled down in 1424.
