The Thames is an amazing archaeological site, much of it accessible to the public. An area of the foreshore by Tower Hill, not usually accessible, was open to the public last weekend during the hours the tide permitted. (Thanks to the Thames Discovery Organisation)
Keen archaeologists donned wellingtons and with buckets of enthusiasm dug the muddy foreshore in search of treasure.
A couple of people were lucky. One woman found a 3rd century Roman coin. This man found a ring, part of a Roman Brooch and a coin.
