An archaeological dig uncovers London's Prehistory
Underground archaeologists found evidence of human existence on the Thames 9,000 years ago, south of London. The discovery of a Mesolithic tool factory included 150 pieces of stone, which have been found in tunnel excavations at North Woolwich. Archaeologists believe that prehistoric Londoners used the site to test and split river pavers that served to make stone tools, transporting them to complete the manufacturing process.
