I photographed these cup-marked stones about 10 years ago. The stones are associated with a Bronze Age burial mound and are no longer visible as they have been buried by Tees Archaeology to protect them from damage/weathering.
The top photo shows a cup marked slab that is thought may have acted as a cover for a cist (stone-lined box). The second and third photos are of a stone that may have been one of a number of kerb stones positioned around the base of the mound.
The mound itself has a large central depression, thought to be as the result of an episode of 19th century barrow digging. In 1817 the Reverend George Young reported the excavation of a tumulus at Upleatham in his History of Whitby. He later donated a small ceramic pot, found during the excavation, to the Whitby Museum.
