For some, it is a nursery rhyme.
For others, it is a piece of history we learnt in school.
Last weekend, the history was brought to life, as the city commemorated the 350th anniversary of the Great Fire.
A giant wooden replica of London back in 1666, floated on the Thames. Crowds watched from the embankment as the 120 metre long replica was set alight. I wish I’d been there to see it.
The historic fire actually blazed for four days and destroyed more than 13,000 wooden properties, homes, businesses and churches.
St Paul’s Cathedral was an icon of the rebuilt city, stone buildings replacing wooden ones. An organised fire service and the insurance industry were other initiatives that resulted from the Great Fire of London.
