In Roman times, and presumably earlier, Thorney Island may have been part of a natural ford where Watling Street crossed the Thames,[1] of particular importance before the construction of London Bridge.
In the Spring of 893, Edward the Elder, son of Alfred the Great, forced invading Vikings to take refuge on Thorney Island.
[3] Despite hardships and more Viking raids over the following centuries, the monks tamed the island until by the time of Edward the Confessor it was "A delightful place, surrounded by fertile land and green fields".
[4] Since the Middle Ages, the level of the land has risen, the rivulets have been built over, and the Thames has been embanked, so that there is now no visible Thorney Island.
[5] Thorney Island is one of the places reputed to be the site of King Canute's demonstration that he could not command the tides, because he built a palace at Westminster.
