After the 1066 Norman Conquest, the manor was taken over by the de Beauchamp family. In 1251 a royal charter was granted to William de Beauchamp to hold a weekly market in Linslade, as well as a yearly 8-day fair. This grant was made on account of a Holy Well or Spring, located to the north of the village, which was a site of major pilgrimage. The holy well, which was a fabricated miracle to bring souls to the shrinking congregation of Old Linslade, was where the canal is sited today not far from the church.
