The London 2012 Summer Olympic and Paralympic Games open on July 27. Among the first to prepare for this historic moment were archaeologists, who excavated a 1.6-square-mile site in east London. Olympic Park, with its stadium, Aquatics Center and Velodome, was later constructed on the land.
Most viewers of the games will see these buildings, not realizing that thousands of years of U.K. history exist underneath the structures.
One of the oldest artifacts to be unearthed was this Neolithic flint axe head.
