Moxby Priory is the commonly used name of the former Augustinian nunnery of S. John the Apostle in today's parish of Marton-cum-Moxby, North Yorkshire, England.
The nunnery occupied grounds around Moxby Hall Farm on the western bank of a bend of the River Foss, about 1500 m ESE of Stillington.The site of the principal claustral buildings is now occupied by a farm, but earthworks of ancillary structures and of the medieval and later garden are still extant and form a historic monument.
[2] Nearby to the West is a spring (St John's Well) which is a source of ferruginous (chalybeate; "ka'LIBATE") waters, long thought to have health-giving properties.
While most double monasteries, of which less than 30 examples have been identified in England, combine the establishments of both the male and the female orders in a single place, Moxby is an even rarer case in that the two parts were housed at completely separate sites.
[3] A double monastery of Augustinian canons and nuns was founded by Bertram de Bulmer in 1158 as the Priory of St Mary at Marton.
