Synopsis: Straddling the ancient highway that is the Thames are both the sealing place of Magna Carta, an ancient scheduled monument that lies under the shade of a 2,000 year old yew tree. Years of archaeological investigation has helped to uncover the hidden stories of these unique twin sites from prehistoric depositions and the lives of medieval nuns to the possible location of the rebel barons' encampment and Tudor to Georgian riverfront mansions .
