Castor House

Castor House is an early 18th century stone house with a rendered front, located on the north side of Peterborough Road in Castor. It features a steeply pitched double span roof with coped gable ends and stands two storeys tall with an attic, comprising five bays. The windows are sashes with glazing bars set in moulded stone architraves that have keyblocks, and there are French doors on the right side of the ground floor. A stone band runs at floor level, and the building has rusticated stone quoins. The central doorway is framed by a moulded stone architrave, a pulvinated frieze, and a cornice. The roof includes three hipped dormers with three-light casements, and the end stacks are made of ashlar with cornices.

Inside, there is a contemporary staircase featuring turned balusters, a moulded rail, square panelled newels, moulded risers, and a moulded open string, along with a fielded panel dado. The south-east room is adorned with ovolo moulded panelling. For approximately 200 years, this house served as the residence of the Bishops of Peterborough, who were also rectors of Castor.
