Leiston Abbey outside the town of Leiston, Suffolk, England, was a religious house of Canons Regular following the Premonstratensian rule (White canons), dedicated to St Mary. Founded in c. 1183 by Ranulf de Glanville (c. 1112-1190), Chief Justiciar to King Henry II (1180-1189), it was originally built on a marshland isle near the sea, and was called "St Mary de Insula". Around 1363 the abbey suffered so much from flooding that a new site was chosen and it was rebuilt further inland for its patron, Robert de Ufford, 1st Earl of Suffolk (1298-1369). However, there was a great fire in c. 1379 and further rebuilding was necessary. The house was suppressed in 1537. A Cartulary or monastic register survives. The Abbey's annual rolls of their court of wreck from 1378 to 1481 are a most important historical resource. A series of late visitations, and a list of abbots, are in Premonstratensian records. The impressive remains of the second abbey stand in the fields to the west of the road going north out of Leiston towards Theberton. After the Abbey was closed the estate was granted to Charles Brandon, 1st Duke of Suffolk. The Abbey became a farm, the farmhouse being built into the abbey walls. A Georgian frontage was added to the house, which was extended in the 1920s. In 1928 the ruins and farm were bought by Ellen Wrightson for use as a religious retreat. At her death in 1946 she bequeathed the house, ruins, land and buildings to the Diocese of St Edmundsbury and Ipswich. It was purchased in 1977 to become the home of the Pro Corda Trust, a centre for the specialized education and training of chamber musicians. The site is managed by them, and is in the guardianship of English Heritage. History The old abbey Ranulf de Glanville, who was born at Stratford St Andrew, married Bertha, daughter of Theobald de Valoines, Lord of Parham. In 1171 he founded the Priory of Augustinian canons at Butley, a few miles south of Leiston, on lands settled upon his wife by her father as a marriage endowment. The Premonstratensian house of Leiston ("Leystone") Abbey was planned less than a decade later, and a received date for its foundation was 1183. Close ties existed between the two houses, and with the Augustinian nuns at Campsey Priory, a de Valoines foundation established shortly before 1195. The site of the
