Sutton Hoo was the granddaddy of all medieval archeological finds, an Anglo-Saxon burial site excavated in 1939 that really captured the imagination like no other find until the Staffordshire Hoard was discovered in 2009.
But we almost lost Sutton Hoo to treasure hunters in the Tudor era. You can read more about that in “Sutton Hoo, Treasure Hunters, and a Lucky Escape” at the British Museum blog.
