Prinknash Abbey (pronounced locally variously as "Prinidge/Prinnish"[1]) (IPA: /ˈprɪnɪdʒ/[2]) is a Roman Catholic monastery in the Vale of Gloucester in the Diocese of Clifton, near the village of Cranham.

In 1096 the Giffard family, who had come to England with William the Conqueror, made a gift of the land to Serlo, Abbot of Saint Peter's, Gloucester.

It remained in the abbey's hands until the suppression of the monasteries in 1541 when it was rented from the Crown by Sir Anthony Kingston who was to provide 40 deer annually to King Henry VIII, who used the House as a hunting lodge.

[4] On 1 August 1928 a Deed of Covenant was made out by the twentieth Earl of Rothes, the grandson of Thomas Dyer Edwardes who had converted to Catholicism in old age, and whose wish was that Prinknash should be given to the Benedictine monks of Caldey Island.

These monks had themselves converted from Anglicanism to Roman Catholicism in 1913 under the leadership of Abbot Ælred Carlyle, although he left monastic life in 1921 to work as a missionary priest in Vancouver.

In 1939 a foundation stone for a new abbey was laid at Prinknash by Cardinal Hinsley, but the Second World War intervened and the previous impracticable building plans were eventually redrawn by F.G. Broadbent.

Dom Stephen Horton, living, is a noted local artist, watercolourist, and portrait painter, and a spiritual father to many people.
