What happened after the Romans left and the Vikings of Jorvik arrived? Two post holes and a jumble of bones may hold a clue

When the great west doors of York Minster swing open on Thursday
 and the Queen makes her way along the nave of the packed church for the
 ancient service of distributing Maundy Money, she will also be walking 
towards a small pit from which human bones have been pouring by the 
barrow load, the remains of some of the earliest Christians to worship 
on the site.
Tantalising finds include 30 skulls and a jumble of 
bones used to backfill a trench by the medieval builders of the present 
cathedral, and a man whose stone-lined and lidded grave was chopped off 
by Walter de Gray's 13th-century walls, leaving only his shins and feet 
in place.
Potentially the most significant finds are two 
nondescript round holes, with groundwater bubbling up through the mud. 
They are post holes that could date from the time of the earliest 
Christian church on the site, after the Roman empire disintegrated in 
the 5th century and before raiding Vikings arrived in the 8th century 
and the Normans in the 11th century.
