Wallington is a town in the London Borough of Sutton situated south south-west of Charing Cross. Prior to the merger of the Municipal Borough of Beddington and Wallington into the London Borough of Sutton, it was part of the county of Surrey. Wallington is a post town in the SM postcode area, and although now part of Greater London, the former postal county was Surrey.
The name "Wallington" derives from the Anglo Saxon "Waletone", meaning "village of the Britons". Wallington appears in Domesday Book of 1086 and was held by William the Conqueror. Its domesday assets were: 11 hides. It had 2 mills worth £1 10s 0d, 11 ploughs, of meadow. It rendered £10. The historic village was situated somewhat to the north of the current town centre around what is now Wallington Bridge over the River Wandle.
What was then called "Carshalton" railway station was opened in 1847 in the open fields to the south of Wallington because the owner of Carshalton Park objected to it being built near to Carshalton village. This acted as a spur to the development of the area and in the 1860s Nathaniel Bridges created a prestigious housing estate of gothic revival villas (architect E. L. Brock) and a new church (Holy Trinity). The area around Holy Trinity Church is known as Wallington Old Town. In particular Clifton Road, Belmont Road and Park Road exhibit some imposing Victorian and Edwardian villas. This southward development continued towards Woodcote and by the time of the First World War the section of Woodcote Road to the south of the station had become the new High Street.
The Municipal Borough of Beddington and Wallington was incorporated in 1936 from the former Beddington and Wallington Urban District. A town hall (architect Robert Atkinson) and public library were built in Wallington town centre in the 1930s, as was the fire station in Belmont Road.
Wallington County Grammar School (for boys) was opened on London Road, close to Beddington Park in 1927.
Wallington was an important centre for the production of lavender oil until about the time of the First World War. Lavender and herb growing were very prominent in the area in Victorian times and much earlier, and extensive fields of lavender were to be seen in the Carshalton, Beddington and Wallington areas. Lavender growing was a very prosperous part of the local agriculture hereabouts in the 19th and early 20th centuries. In Wallington the area to the north of the station was chiefly used. The scale of the operation can be understood from the fact that the Daily News in 1914 was able to state that at nearby Carshalton Beeches “In every direction the low hill sides of the farm beyond Beeches Halt are swept with the bloomy pastel tint of the lavender flowers”. The importance of lavender is remembered and commemorated in a number of ways, for example:
