Coordinates: 51°04′41″N 1°51′22″W / 51.07808°N 1.85600°W Wilton Abbey was a Benedictine convent in Wiltshire, England, three miles from Salisbury on the site now occupied by Wilton House.
A first foundation was made as a college of secular priests by Wulfstan, Ealdorman of Wiltshire, about 773, but after his death (802) was changed into a convent for twelve nuns by his widow, Saint Alburga, sister of Egbert of Wessex. Owing to the consent given by this king he is counted as the first founder of this monastery. Saint Alburga herself joined the community, and died at Wilton. King Alfred, after his temporary success against the Danes at Wilton in 871, founded a new convent on the site of the royal palace and united to it the older foundation. The community was to number 26 nuns. It was attached to St Mary's Church. Two daughters of king Edward the Elder and Ælfflæd, Eadflæd and Æthelhild, probably joined the community, Eadflæd as a nun and Æthelhild as a lay sister. They were buried at Wilton with their mother. Their half-brother, king Æthelstan, made two grants of land to a congregation at Wilton in the 930s, including one in 937 for the remission of his sins and those of Eadflæd.
