Harrowden is mentioned in the Domesday Book of 1086, though by the 13th century the area became known as Eastcotes or Cotes. The name derives from the Old English name for a cottage - 'cotum'. Harrowden has just 18 houses and 32 people on the electoral roll. Elstow Brook runs through it. There is just one road - Old Harrowden Lane - which leads to a footpath known as Bumpy Lane, from where you can access the birthplace of John Bunyan, now simply marked by a stone.
