Isleworth

Isleworth ( /ˈaɪzəlwɜrθ/) 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'.

Isleworth's former Thames frontage of approximately one mile, excluding that of the Syon estate, was reduced to little over half a mile in 1994 when a borough boundary realignment was effected in order to unite the district of St Margarets wholly within London Borough of Richmond upon Thames. As a result, Isleworth's boundary with the Thames is now almost entirely overshadowed by the 3.5-hectare (8.6-acre) islet of Isleworth Ait. The River Crane flows into the Thames south of the Ait, and its distributary the Duke of Northumberland's River west of the Ait.
