Walthamstow Market, in the London Borough of Waltham Forest, is the longest (though not the largest) outdoor market in Europe. It occupies all but the last of Walthamstow's High Street. It is reputed to be a mile long, but in fact measures approximately one kilometre. History and characteristics of the area The 19th century Marsh Street, a rural lane, was transformed into the High Street by Victorian expansion. The street market dates from 1885. Today it is the centre of Walthamstow, with the main rail and tube station, bus station, post office and Central Library, and most of the commercial development and activity located around the High Street. Five days a week (Tuesday - Saturday), the High Street is dominated by Walthamstow Market, and Saturdays are crowded. The Town Square, adjacent to the main market, is home to an occasional Saturday French market. On Sundays the street is quieter, with some shops and cafes open. There is a Sunday morning farmers market at the Town Square. The street market stretches the entire length of the High Street, apart from the last 100 metres of the street, and has about 500 stalls. The street is lined with shops of different sizes, from small traditionally sized shops to large supermarkets. Generally, the shops do not extend into the side streets, which are densely populated with terraced houses. The High Street area has a diverse, ethnically mixed population. Forty-one per cent of residents (in the ward as a whole) are classified as black or minority ethnic, mostly Pakistani and African-Caribbean. The market has kept a traditional cockney feel whilst absorbing influences from the diverse cultures of the area. The overall tone is downmarket but with many interesting and enjoyable aspects. High street chains There are two main areas of new building along the High Street beside the market, each containing a supermarket* Sainsbury's supermarket is set in a development which includes a few other shops, which use the street frontage that Sainsbury's does not need, and a two-storey car park above. There is a lift connecting the public car park to the supermarket. The Mall Selborne Walk is a much larger complex with shop frontages on the High Street, and an indoor shopping mall. Most of the units are chains, the largest being Asda supermarket. Selborne Road, which runs parallel to the High Street, provides access for cars and buses. On that side
