Walcot Hall is a Grade I listed Carolean country house in the civil parish of Southorpe, Cambridgeshire, England. It lies 2 km (1 mile) south east of the village of Barnack. The house is now within the boundary of the Peterborough unitary authority area of the ceremonial county of Cambridgeshire but it was part of the Soke of Peterborough, an historic area that was traditionally associated with Northamptonshire.
The house is constructed of limestone ashlar in two storeys plus attic with a rectangular floor plan of nine bays by five and a Collyweston stone slate hipped roof.[1] It stands in some 120 acres of wooded parkland as part of a 1400-acre agricultural estate. In the grounds are two temples by William Henry Ansell.[2] The stables, north lodge and associated structures are Grade II listed.
