Isleworth: is a small town of Saxon origin sited within the London Borough of Hounslow in west London, England. It lies immediately east of the town of Hounslow and west of the River Thames and its tributary the River Crane. Isleworth's original area of settlement, alongside the Thames, is known as 'Old Isleworth'. The north-west corner of the town, bordering on Osterley to the north and Lampton to the west, is known as 'Spring Grove'.
Roman and Anglo Saxon: Excavations around the eastern end of the Syon Park estate have unearthed evidence of a Romano-British settlement. 'Gislheresuuyrth', meaning in Old English Enclosure belonging to [a man called] Gislhere, is first referred to as a permanent settlement in an Anglo-Saxon charter in the year 695. The Domesday Book says that during the reign (1042-1066) of Edward the Confessor the manor belonged to Earl Algar (Anglo-Saxon spelling probably Elfgar), and a modern road off South St today carries his name.
