On the death of Margaret de Clare in 1312, the manor of Isleworth passed to the Crown. Manorial accounts refer to several residential buildings arranged around a courtyard, and included the royal chambers, hall, kitchen, and chapel. Without the court was an outer courtyard containing barns and other outbuildings. In 1421 the manor house and manor were granted to the new Bridgettine foundation at Syon. A moated site exists at TQ153754 and may be the remains of this site (HKW). (PastScape 1393703)
Homestead moat, on the N. side of the road 1m W.S.W. of the church, has been almost entirely filled in (RCHME). A square moat with the entrance on the east side (VCH). (PastScape 397857)
For some time the power of the merchant oligarchy had been threatened by the populace, who had installed a democratic mayor, Thomas Fitz-Thomas, in 1263. Led by Hugh Despenser, the baronial justiciar, and with their own constable and marshal elected for the occasion, they made straight for Richard's manor of Isleworth, which he had surrounded with a ditch and stockade. They broke the head of the fishpond which he had constructed, at great cost, and destroyed everything that they could not steal. (Denholm-Young 1947)
