Research shows that British royal tombs dating from the 5th to the 7th centuries AD have been abandoned until now, possibly because they are not meticulously decorated and do not contain anything valuable, according to Live Science.
The study reviews archaeological evidence from an unknown historical period of England, from the late ancient Grecian regions to the late Anglo-Saxon kings - the period described in the legend of King Arthur.
There may be up to 65 tombs of British kings and their families in 20 cemeteries in the west of England and Wales, including modern England parks of Somerset and Cornwall, according to research.
The British continues to rule in today's region's west, Wales and part of Scotland for centuries after the end of the Romans' rule in the UK in the early 5th century, while Anglo-Saxon settled in the East.
But while the Anglo-Saxon kings of that time were elaborately buried with sophisticated and valuable decorations, the English converted to Christmas considered this a pagoda custom. The British seem to have buried royal residents without even stone steles.
