Thorpe Hall at Longthorpe in the city of Peterborough, Cambridgeshire, is a Grade I listed building,[1] built by Peter Mills between 1653 and 1656, for the Lord Chief Justice, Oliver St John.

Parliament disposed of Church property to raise money for the army and navy and the parliamentarian Oliver St John bought the lease to the manor of Longthorpe and built Thorpe Hall.

In 1654 it was described by the author John Evelyn as "a stately place...built out of the ruins of the Bishop's Palace and cloisters.

[5] Thorpe Hall is situated in a Grade II listed garden that is open to members of the public throughout the year.

The late 19th-century lodge,[9] octagonal summerhouse in red brick with fish scale slate roof,[10] and a free-standing archway resembling a Venetian window in design[11] are Grade II listed buildings.
