Netley Abbey is a ruined late medieval monastery in the village of Netley near Southampton in Hampshire, England. The abbey was founded in 1239 as a house for monks of the austere Cistercian order. Despite royal patronage, Netley was never rich, produced no influential scholars nor churchmen, and its nearly 300-year history was quiet. The monks were best known to their neighbours for the generous hospitality they offered to travellers on land and sea.
