[1] This establishment did not last long, however, and following its demise the manor of Langley and St Algar's chapel were transferred to Cirencester Abbey.

The priory also continued to make acquisitions and receive donations in order to improve its revenues.

[1] Longleat Priory had no motherhouse; instead, it was controlled as a peculiar (an extra-diocesan place of worship) by the Dean of Salisbury,[1] who held ultimate control over the priory and had to give his consent to the canons' choice following their election of a prior.

[1] Dean (and later Bishop) of Salisbury John Chandler visited the Priory on 1 October 1408, having four years earlier given his permission to the canon's elected prior, Peter Sampson.

The priory was suppressed in 1529, six years before King Henry VIII's dissolution of the lesser monasteries in 1535.

[1] Its land and property were sold or transferred to the Carthusian Hinton Priory in Somerset, and in 1534 was recorded as providing them income of £21 16s 8d.
