Leytonstone (/ˈleɪtənstoʊn/ LAY-tən-stohn) is an area in East London, England, within the London Borough of Waltham Forest. It adjoins Wanstead to the north-east, Forest Gate to the south-east, Stratford to the south-west, Leyton to the west, and Walthamstow to the north-west, and is 7 miles (11 km) north-east of Charing Cross.
Historically, it was part of the ancient parish of Leyton in the Becontree hundred of Essex. The first documented evidence of settlement is from the 14th century, describing a hamlet at 'Leyton-atte-stone'; a reference to the Roman milestone located within the area, that formed a northern boundary of the parish. It remained largely rural until the 19th century, becoming part of the London postal district in 1856, the same year its railway station was opened (now on the Central line). When Greater London was created in 1965, the Municipal Borough of Leyton merged with Chingford and Walthamstow to form the London Borough of Waltham Forest.
