DIGGING OLYMPIC SIZED HOLES By Kieron Tyler Kieron works for the Museum of London Archaeology Service and in partnership with PCA (Pre-Construct Archaeology he’s heading up the excavations of London’s Olympic site. He’s hoping archaeologists will find evidence of original prehistoric Londoners right through to Roman, Viking, medieval and relatively recent industrial activities. For Kieron it’s a huge task, but he hopes that the findings will give a better insight into how the lower Lea Valley was used.
