Archaeologists uncovered four skeletons in Iron Age graves on the site of the London 2012 Olympic Park.
The graves were in an area of a buried settlement on the site of the Aquatics Center. The remains were removed for further study and one, estimated at 3,000 years old, was exhibited Thursday by the Olympic Delivery Authority.
The finds follow that of a Roman coin, Roman river walls, World War II gun emplacements and a 19th-century boat used for hunting on the River Lea, which joins the Thames near the Olympic site.
The Olympic site is covered mainly by industrial development, but 3,000 years ago was an open river valley.
More than 140 trenches have been dug and investigated as part of archaeological work on the sites of the Olympic Stadium, Aquatics Center, VeloPark, Olympic Village and the media center.
