Gustav Milne, a Thames waterfront specialist from the Institute of Archaeology, UCL, is something of a local expert and well renowned in archaeological circles as a leading authority on the river.

'The Thames is a fundamental part of the history of London,' says Gustav. 'The remarkable thing is that we know so little about it. I've spent the last 25 years of my life exploring the Roman and medieval Thames and that's been a revelation to me. Here on this project we were actually trying to go back to over 3,000 years ago. We found lots of new stuff doing this project and the whole thing was very interesting'.
