Baldock is a historic market town in the local government district of North Hertfordshire in the ceremonial county of Hertfordshire, England where the River Ivel rises. It lies 33 miles (53 km) north of London, 15 miles (24 km) southeast of Bedford, and 14 miles (23 km) north northwest of the county town of Hertford. Nearby towns include Royston to the northeast, Letchworth and Hitchin to the southwest and Stevenage to the south.
Paleolithic, Neolithic and Bronze Age settlements show the site of Baldock has been continuously occupied since prehistoric times.
At the beginning of the Iron Age there was a hillfort at Arbury Banks, 5 km to the northeast of Baldock, that dominated the area. In the Late Iron Age (c. 100 BC), the local power base shifted from the hillfort to the vicinity of Baldock. The soil was easily farmed and transportation was more convenient. In the Roman and late Roman eras the community appears to have been both a market town and religious centre. The Roman settlement gradually disappeared. There is no entry for Baldock in the Domesday Book.
