Manor. This monastery was of French monks, who refused to pray for Henry V following his warring with France, probably at Agincourt in 1415, and was therefore dissolved by the King almost immediately after its foundation. It probably occupied the site in Isleworth to which Syon Monastery moved in 1431. The Monastery of St Saviour and St Bridget of Syon, of the Order of St Augustine (1415) Syon Monastery, sometimes called Syon Abbey. The first and original site of this monastery was probably almost due west of Sheen Palace, across the river, on the left bank of the Thames in Twickenham Parish. The House of Jesus of Bethlehem of Sheen, of the Order of Carthusians (1414) Sheen Priory, the subject of the present article, built within Sheen Manor, to the north of the new palace. Establishment of the priory In 1414, Henry V established the priory, designated "The House of Jesus of Bethlehem of Shene", for 40 monks of the Carthusian order. It was built approximately half a mile to the north of the existing royal manor house or palace, and had 30 cells round a great court or cloister. The priory's endowments at its foundation included the church and rectory estate at Winterbourne Stoke, Wiltshire. Nomenclature During the reign of King Henry VII (1485–1509), formerly styled "Earl of Richmond", the former royal manor house or palace of Sheen built by King Henry V was replaced in 1501 by a royal palace which was renamed "Richmond Palace" in honour of Henry VII. The name of the manor itself was likewise changed from "Sheen" to "Richmond". The name of Henry's earldom derived from his former stronghold, Richmond Castle in Yorkshire, itself named after Riche Mont (Rich Mountain) in France. The Priory of Sheen, although it then found itself within the newly renamed manor of Richmond, nevertheless retained its ancient appellation of "Sheen", being a religious establishment, the function of which was ostensibly the glorification of God not, as in the case of the new secular palace, of the new King and Tudor dynasty, victorious after the Battle of Bosworth in 1485. In 1500, at the command of Henry VII, the town of Sheen, which had grown up around the royal manor, was renamed Richmond, whereupon the entire ancient manor too, in which the new palace stood, became known as Richmond rather than Sheen. The ancient Manor of Sheen is now situated
