The palace is just one of a dozen structures that ground penetrating radar surveys picked up on the Tintagel peninsula, some of which likely housed workman, soldiers and artists. Whoever lived in the main structure, however, lived a pretty glamorous lifestyle considering it was the dark ages. The researchers have evidence that they drank wine from the geographic area known as Turkey today, and used olive oil from the Greek Isles and Tunisia. They drank from painted glass cups from France and ate off plates from North Africa.
If I remember my T.H. White (and Thomas Malory and Mary Stewart) correctly, Tintagel was the castle of Duke Gorlois of Cornwall, whose wife Igraine was coveted by Uther Pendragon. The obsessed King Uther Pendragon besieged the castle without success, so he resorted to magic. Merlin cast a spell that caused Uther to take on the form of Gorlois. Gorlois was lured out of the castle, whereupon Uther rode in and convinced Igraine he was her husband. Nine months later, Arthur was born and given to Sir Hector to raise as the boy “Wart”. No one but Merlin knew Wart’s real parentage until Wart came upon a sword stuck in a stone. . .
Later, Gorlois and Igraine’s daughter Morgause seduced Arthur and gave birth to the horrible Mordred, who would rebel against his father/uncle.
I try to read The Once and Future King every other year. My sister and I have memorized most of Monty Python and the Holy Grail, so we can ward off boredom with phony French accents and the Camelot song.
