In 1155 Bloxham was divided in two manors. In 1269 the half later called Bloxham Beauchamp was given to Queen Eleanor, and later bestowed upon Edward III's chamberlain Roger de Beauchamp and sold in 1545 to Richard Fiennes, 6th Baron Saye and Sele. The other half, called Bloxham Fiennes, was passed to Amaury de St Amand, came to be called Saint Amand's, and was subsequently sold to Thomas Wykeham and reunited with Bloxham Beauchamp when Baron Saye and Sele inherited it. Beauchamp Manor stood roughly on the site of Park Close and the Manor of St Amand was on the area now occupied by Godswell House. Although neither manor remains, the dovecote of St Amands is still visible next to Dovecote House. By the 15th century St Mary's Church, Bloxham had become one of the grandest parish churches in southern England, showing Bloxham's medieval wealth.
