To enforce his rule, Laughton castle was among a number that Busli had built in the late 11th century. The motte and bailey with a high mound with a by inner bailey was surrounded by large earthworks and an outer ditch. An outer bailey, which is now the churchyard of the 14th century All Saints parish church, also had substantial earth ramparts and a dry ditch. It's believed that Busli built his castle on the site of the Saxon hall by Mercian Earl, Edwin.
