Northampton began around the Chalk Lane, St Peter’s Street area. It is thought that before the Castle there was some sort of Saxon/Danish defences here, and in that period the town was surrounded by an earthwork.
It appears that Waltheof, Earl of Northampton at the time of the Norman conquest was ordered by William the Conqueror to build a castle here. This was probably a wood and earthen structure called a motte. In 1072 Waltheof was executed, later the title was granted to Simon de Senlis and he built the stone castle. It appears that the new Castle was well under way when Senlis went on the crusade in 1095.
