Bedfordshire is a county of south-eastern England lying to the north of London and bounded by Northamptonshire, Cambridgeshire, Hertfordshire and Buckinghamshire. The topography is mainly low-lying, with some fenland areas in the east of the county. The county town is Bedford, home of John Bunyan, but the main urban centre is the industrial and university town of Luton. Major industries include motor manufacture in Luton and brick manufacture in the north of the county; the need of the brick industry for labour led to the immigration of many people from Italy in the years following the Second World War.
