The Hoxnian Stage was a middle Pleistocene stage of the geological history of the British Isles. It was an interglacial which preceded the Wolstonian Stage and followed the Anglian Stage. It is equivalent to Marine Isotope Stage 11. Marine Isotope Stage 11 started 424,000 years ago and ended 374,000 years ago. The Hoxnian is divided into sub-stages Ho I to Ho IV. It is likely equivalent to the Holstein Interglacial in Central Europe.
Hoxne is a village in the Mid Suffolk district of Suffolk, England, about five miles (8 km) east-southeast of Diss, Norfolk and 1⁄2 mile (800 m) south of the River Waveney.

Swanscombe Skull Site or Swanscombe Heritage Park is a 3.9-hectare (9.6-acre) geological Site of Special Scientific Interest in Swanscombe, north-west Kent, England. It contains two Geological Conservation Review sites and a National Nature Reserve. The park lies in a former gravel quarry, Barnfield Pit, which is the most important site in the Swanscombe complex, alongside several other nearby pits.
Wansunt Pit is a 1.9-hectare (4.7-acre) geological Site of Special Scientific Interest in Dartford Heath between Crayford in the London Borough of Bexley and Dartford in Kent.
