In 1485, King Richard III was defeated at the Battle of Bosworth Field by Henry Tudor, putting an end to the Wars of the Roses. After the battle, Richard's body was stripped and subjected to various degradations so that his men might know how badly they had lost. Eventually, however, the body was recovered by his loyal followers and buried in the Greyfriars Church in Leicester.
Over the centuries, however, the church fell into disrepair and its whereabouts were forgotten. Now archaeologists believe the site of the Greyfriars Church is under a parking lot. They have yet to determine the precise location of the church, let alone Richard's grave within it, but it is a project the team plans to undertake with enthusiasm.

Update: The church has evidently been discovered. See your Guide's news item for more details.
