Medieval London

S1 E1: The sheer amount of sludge and excrement festering in the streets of London 700 years ago is hard to conceive. Historian Dan Snow foolishly decides to spend the night as a medieval muckraker shifting a staggering six tonnes of waste. Medieval Londoners were forced to mount wooden platforms to avoid the disgusting mess underfoot, but Dan discovers the modern city was built on this filth.
