Potters Bar is located in the county of Hertfordshire, approximately 12 miles north of London and 20 miles south of Stevenage.
The name Potters Bar is of uncertain origin. The Potters component of the name is thought to derive from evidence of a Roman pottery sited in the area, or from the family Pottere who lived in the South Mimms parish. The Bar component is thought to refer to the gates leading from the South Mimms parish and into the Enfield Chase parish, or possibly from some sort of toll on the Great North Road. The original “Bar” is said to have been at what is now the Green Man pub, or at the current entrance to Movern House. In 1387 the town was recorded as Potterbare.
