Hatfield Manor House, in the village of Hatfield near Doncaster, is largely a Georgian building, but with clearly surviving structures from previous eras (e.g. lancet windows).
It is believed to be the site of the palace of Edwin of Northumbria, who allegedly died at the Battle of Hatfield Chase, the location of which is disputed.
The building is not open to the public, the entrance is marked by two modern gatehouses on Manor Road, the early 18th century stables are clearly visible from the road.
