In 2012, archaeologists dug up a parking lot in Leicester, England, and found the skeleton of King Richard III — lost for 527 years. He was the last English king killed in battle, buried in a hasty unmarked grave in 1485. An amateur historian convinced a university to dig up the car park on a hunch. They found him in the first trench, six hours into a two-week excavation. The parking space above his grave was marked with the letter "R."
