History has a habit of making the Middle Ages look surprisingly tidy. The Romans disappear. Castles start to appear (everywhere). Knights arrive. Everyone starts speaking in suspiciously Shakespearean English. Lots of fighting. That's not what happened.

On the morning of 14 October 1066, King Harold Godwinson stood on a ridge in Sussex facing an invading army led by William, Duke of Normandy. By sunset, Harold was dead. England would never be the same again.

Because medieval London, the London of knights and sieges and plague and enormous political drama, is not gone. It is not buried under glass offices and coffee shops, lost entirely to the Great Fire of 1666 and the Blitz and two thousand years of continuous rebuilding. It is hiding in plain sight. In churches, in ruins, in underground rooms, in a meadow beside the Thames, in two giant wooden statues paraded through the City every November.
