ALTHORPE MANOR

Identity: confirmed — The National Archives record F291847 identifies Althorpe Manor at Althorpe, Lincolnshire, and its associated court-roll references concern the same manor. The documented former manor house known as The Old Hall is located in Althorpe and is therefore the best surviving physical identification of the manor centre.
Representative point: 53.5766, -0.7420
Basis: documented_manor_house — The Old Hall, Main Street, Althorpe, is a Grade II listed former manor house, described as a mid-seventeenth-century building possibly incorporating earlier fabric. The published listing gives approximate coordinates 53.5766, -0.7420 (OS grid SE833096).
Point confidence: high
Boundary status: representative_point_only
Boundary period:
Boundary confidence: none
Boundary basis: The accessible evidence establishes the manor house and indicates a historical relationship between Althorpe and Keadby, but does not provide a sufficiently explicit, manor-specific perimeter. The former parish, enclosure-map areas, and modern civil-parish boundaries cannot safely be substituted for the manorial extent.

Warnings / uncertainty:
- No defensible historical manor polygon was found in the accessible evidence.
- The historical extent may have included land in or associated with Keadby, but this is reported as likely rather than conclusively mapped.
- The former Althorpe parish and later Keadby-with-Althorpe civil-parish boundaries must not be treated as the manor boundary.
