Amazing - 6,000 years ago someone threw this magnificent flint ax head into the river Lea deliberately, perhaps as an offering to the river gods. It was unearthed by archeologists ahead of the construction of the Olympic Park and is now coming home to the Museum of London.

Pre-construction archeological work led by Museum of London archeologists started in 2004. The site is the largest redevelopment in London in modern history - an area almost the size of the City of London was reworked. The archeologists’ finds are amazingly diverse, including Neolithic ritual activity; ancient Roman riverbank revetments and Bronze Age field systems; 19th-century railways and canals; medieval mills and WW2 defensive structures. Without the construction of the Olympic Park all this history would lie undiscovered.
