Alnwick Abbey was founded as a Premonstratensian monastery in 1147 by Eustace fitz John near Alnwick, England, as a daughter house of Newhouse Abbey in Lincolnshire. It was dissolved in 1535, refounded in 1536 and finally suppressed in 1539. The Alnwick Abbey site is located just within Hulne Park, on the bank of the River Aln. The only visible remnant is the impressive 14th century gatehouse.
Eustace fitz John became lord of the barony of Alnwick by his marriage with Beatrix, the daughter of Ivo de Vesci. He endowed it amply. The charter of foundation, included in a confirmatory charter of Henry Percy, Earl of Northumberland, is addressed to William of St. Barbara, Bishop of Durham. Among the souls for whose benefit it was erected, is mentioned that of Ivo de Vesci. Dugdale and Stephens do not agree touching the time when this order of Religious came first into England. From Dugdale's authority, it is said that the first of that order came to settle at Alnwick in the year 1147; but Stephens, from the authority of Raynerus, says the order first came over in 1146, and settled at Newhouse, in Lincolnshire, in their monastery built by Peter de Saulia, dedicated to St. Martial.
In the chronicle of this house, preserved in the library of King's College, Cambridge, there is an account of a banquet given by Walter de Hepescotes, the abbot, A. D. 1376, on the day of the Assumption of the Blessed Virgin Mary, to Henry the 4th Lord of Alnwick, with the thirteen following knights, William de Acon, Richard Tempest, Walter Blount, Allan de Heton, John Conyers, John Heron, John Littleburum, Thomas de Ilderton, Thomas de Boynton, Ingram de Umfravil, John de Dichaunt, John de Swynton, Radulphus de Viners, and many others of the chief gentry of the country, amounting to 120, all entertained in the refectory; in addition to eighty-six at a second repast. The cloisters too were filled with commoners of all ages, to the number of 1,020, who were likewise there feasted.
