Staines-upon-Thames

Staines-upon-Thames, commonly known simply as Staines, is a market town in northwest Surrey, England, around west of central London. It is in the Borough of Spelthorne, at the confluence of the River Thames and Colne. Historically part of Middlesex, the town was transferred to Surrey in 1965. Staines is close to Heathrow Airport and is linked to the national motorway network by the M25 and M3. The town is part of the Greater London Built-up Area.

The earliest evidence of human activity in the area is from the Paleolithic and, during the Neolithic, there was a causewayed enclosure on Staines Moor. The first bridge across the Thames at Staines is thought to have been built by the Romans and there was a settlement in the area around the modern High Street by the end of the 1st century CE. Throughout the Middle Ages, Staines was primarily an agricultural settlement and was held by Westminster Abbey. The first surviving record of a market is from 1218, but one may have taken place near St Mary's Church in the Anglo-Saxon period.
