London tornado of 1091
The London Tornado of 1091 is reckoned by modern assessment of the reports as possibly a T8 tornado which occurred in London in the Kingdom of England and was the earliest reported tornado in that area, occurring on Friday, 17 October 1091. The wooden London Bridge was demolished, and the church of St. Mary-le-Bow in the city of London was badly damaged; four rafters long were driven into the ground with such force that only protruded above the surface. Other churches in the area were demolished, as were over 600 houses. For all the damage inflicted, the tornado claimed just two known victims from a population of about 18,000.
William II of England was King at the time of the tornado; it is unknown if he was present in the area during the storm.
