A Dark Age palace has been uncovered on Cornwall's windswept coast, strengthening the likelihood that the legend of King Arthur may be based on a grain of truth.
Myth has it that King Arthur will return at the hour of Britain's greatest need. It could certainly do with some help right now.
Whether or not a new archaeological dig at his supposed birthplace of Tintagel Castle will prompt such a second coming is another matter.
But it may already be adding to the evidence that the myth surrounding the warrior king who, with the knights of his roundtable, struggled to hold back a "Dark Age" from enveloping Britain.
The Dark Age has long since proven to have been not so dark. But the scant records from the time have made pinning down one historical character that best fits the outline of the tale near impossible.
Last month they sank four trenches into previously unexcavated areas of the ancient island settlement.Now, archaeologists have returned to Arthur's traditional birthplace of Tintagel for the first time since the 1990s. They've just completed their first dig in a new five-year excavation.
What they found may be the remains of a 1500-year-old palace.
BIRTHPLACE OF A LEGEND
Like many prominent British landmarks, Tintagel has long been associated with Arthurian legend.
Like all the others, the evidence has been largely limited to hearsay.
The ruined castle that dominates the Tintagel landscape is believed to be from the Medieval 13th century. This would make it some 700 years younger than the Arthurian tales.
But it's long been thought that the castle may have itself been built upon the ruins of an older structure.
But it was the discovery of a stone engraved with a name linked to Arthur's in 1998 that reinvigorated interest in the windswept ruins on Cornwall's coast.
Archaeologists believe it to have been a foundation/dedication stone dating from the 6th century. It is engraved with the name Artognou.
It's these ruins that may have been linked to the Arthur of legend.
The tales tell of the seduction - some say by magical means - of the beautiful wife of a local lord by the then King of Britain. The illicit act conceived Arthur.
Mythology goes on to say the young boy was raised as a squire - a knight's assistant - until fate took its hand and placed the rightful king on his throne.
The first written record of the mystic king comes from a monk named Gildas in the sixth century.
But it was a time where books were scarce and the most common form of transmitting history - and telling tales - was through memorised songs and poetry.
It took two several more centuries before a more detailed account of King Arthur and his actions would be recorded by Geoffrey of Monmouth in 1138AD.
Unwinding his tangle of myth, legend and history has been a challenge for authors and historians ever since.
At the time of Monmouth's writing, historians believe Tintagel would likely have been little more than a windswept pile of rubble.
So the notion of it being a powerful palace would have had to have been handed down verbally through the generations.
Just like the tale of Arthur himself.
SCRATCHING THE SURFACE
The archaeologists were guided in their efforts by geophysical surveys of the rocky outcrop's terraces earlier this year.
Among the ultrasound and radar echoes were outlines of what could be up to a dozen buried buildings, one-metre thick walls and winding paths.
The strategically positioned trenches, two on an upper east terrace and two to the south, have all provided a glimpse of the stonework foundations of long-lost buildings.
From the scattering of potsherds and glass, this places the site smack between 400 and 600AD - precisely the time Arthur is supposed to have led his war band against the invading hordes.
None of this proves Arthur existed.
But the new finds add substance to the idea that the site could have produced cultured but strong warriors as well as influential political figures.
It would have been a beacon of lost civilisation in a world of economic chaos and roving, marauding tribes.
Much of the 150 fragments of glass and pottery recovered had been imported from the far reaches of the then collapsing Roman Empire - indicating a place of both great wealth and trade importance.
One piece was the lip of a Turkish-Phocaean red-slip plate or bowl. It was a particularly fine and highly prized ceramic that would likely have held pride of place on the table of nobility.
Original excavation work in the 1930s led archaeologists to believe the cliffside landmark may have once been an Early Christian monastery.
Later work has steadily strengthened the idea that it may have been an important Dark Age fortress, held by the king of Dumnonia who filled the void in Cornwall left when the Romans abandoned Britain in 410AD.
