Somerton Castle and outbuildings, Castle Lane, Boothby Graffoe - North Kesteven

Early C14 castle with C17 farmhouse and later outbuildings. The extensive property had fallen into disrepair and the farm buildings were largely redundant. A new owner is undertaking a major repair and conversion project. This has been informed by thorough surveys and archaeological investigations, and advised by the Local Planning Authority and Historic England. The repair and refurbishment of the house has been undertaken and the ruined northeast tower has been repaired. Excellent progress is being made towards removing the site from the HAR Register.
