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 killed at the Battle of Bosworth in 1485, the last English king to die in combat. His body was buried in a hasty, unmarked grave at Greyfriars friary. When the friary was demolished in 1538, the grave vanished. Centuries later, the site became a city council car park. An amateur historian named Philippa Langley convinced the University of Leicester to dig it up on a hunch. They found him in the first trench, six hours into a two-week excavation. DNA testing confirmed the identity with 99.999% accuracy. The skeleton showed 11 battle wounds — nine to the skull. The parking space above his grave was marked with the letter “R.”
