This is the site of King Arthur’s Court in the later legends. But, setting aside the issue of trusting later stories, Arthur still needed to live somewhere. And a well-fortified dwelling makes a certain amount of sense for a war leader.
One good possibility is a hillfort now called Cadbury Castle, in Somerset, long associated with Camelot in local legend.

Yeah, it’s not on this map, yet. In fact, I think I’m going to need to redo some of the locations on this map, anyway.
The “bury” part, at least is Saxon, not British and may date to a much later Saxon mint on the site. It’s impossible to tell, now, what the Britons called it in the fifth century, though it is near the villages of Queen’s Camel and West Camel and the River Cam (a tributary of Yeo) runs by it, so Camelot may be a Norman French mispronunciation of it. Something with “Camel” as part of the name is more than reasonable.
Four rings of ditch-and-embankment earthworks encircle the hill, providing access only from the southwest and northeast. These walls protected an area of about 18 acres. The Iron Age hillfort was abandoned during the period of Roman control. Like several other such hillforts, it was reoccupied during the Dark Ages, after the Romans left. Unlike the others, it was not only reoccupied, but refortified—and the new fortification were unusual.
Around 470, a stone wall or ledge was added to the top of the innermost earthwork. Above that, a timber wall protected a parapet and spanned the gate.
Inside these defenses, on top of the plateau, were several buildings, including a timber great hall about 63 feet long by 64 feet wide. And, like Tintagel, there’s evidence of luxury items from the Mediterranean, marking this as a high-status dwelling.
A highly suitable dwelling for a war leader. And, as far as is known so far, Cadbury Castle was the only site refortified in this manner during the Dark Ages.

Thankyou Meredith !
This response might be a bit late(it’s now 2022)…but I only just came across your site…sorry!
I normally avoid “Arthurian” authors like the plague…to much playing “foot loose and fancy free” with the facts, all in the name of a good “Narrative”…But something about your Post caught my attention….perhaps it’s as simple that You Write Damn Well!
…Oh gosh, damn it, now I have to keep an eye out for books… Love and Best Wishes to you Meredith.
