Thetford Warren Lodge was probably built around 1400 by the Prior of Thetford. As a defensible lodge, it protected gamekeepers and hunting parties against armed poachers. Later it was used by the local ‘warreners’ who harvested rabbits here. It also served as a Leper house.
It is said to be haunted by the ghost of a leperosy sufferer.
