Dan Jones, Suzannah Lipscomb, and Rob Bell examine the Great Fire of London, which swept through the city in September 1666, and the rebuilding process that took place in the years afterwards, accelerated by the Industrial Revolution. Suzannah also investigates how London's West End became the playground of the wealthy elite, and established itself as the best-known shopping district in the world.
