Road workers in Britain have accidently discovered an underground chamber that is believed to be the site of the earliest christian burial with archaeologists calling it the Anglo-Saxon equivalent of King Tutankhanmun’s tomb.

The chamber, originally uncovered between a road and a railway line in the south-eastern English village of Prittlewell in 2003, has turned out to be a 1,400-year-old tomb.

New details have been published about the finding, which archaeologists say is the most important Anglo-Saxon burial discovery in more than 70 years.
