Two mounds (Mound 1 and 2) have each been considered to be the grave of Raedwald, king of East Anglia from 599 to 625 AD, but there is considerable doubt about the attribution. Sutton Hoo Mound 1 has also been mentioned as the burial place of Beowulf, but of course, Beowulf was a fictional Scandinavian.
The most recent excavations at Sutton Hoo were conducted by the Suffolk County Council Archaeological Service under the direction of Martin Carver at the University of York.
