A major part of the celebrations of the 350th Anniversary of the Great Fire of London was the dominoes - three routes (6km) through the city with 23,000 breeze blocks. I followed the route from Cheapside, through churches, down and up steps, over roof tops and finally at Paternoster Square by St Paul's Cathedral where it finally burst into flames. It poured with rain, but I had a my waterproof with hood. Simply stunning how it was done.
