As for Gorlois himself, he made a rather unwise decision to sally forth himself from his extremely defensive position and got himself killed. When news of his death (and especially the time and manner of it) reached Tintagel, all within questioned what they had really seen. Uther wasted no time in boasting that he had control of the situation and acted before anyone could think twice: In no time at all, Ygerna was queen. She stayed at Tintagel Castle for the birth. What happened next? Geoffrey doesn't say; he skips ahead to Arthur the king at age 15. Other traditions say that Merlin came to get the baby and kept him hidden from his detractors until the time is right.
Tennyson makes Tintagel the home of King Mark and later his queen, Isolde. As the story ends tragically, Tintagel is also the burial place of Tristan.
For Arthurian purposes, Tintagel Castle has served its purpose. We hear more of it in passing several times but almost always in reference to the story of Arthur's begetting and birth. Supposedly, Cador took over the castle when he took over Cornwall.
The castle as described by Geoffrey, of course, did not exist. It was just another example of Geoffrey's applying his times to the story at hand. A medieval castle was built on the site, but it wasn't completed until three years after Geoffrey published the Historia regum Brittanie. Where did Geoffrey get his description? Good question. The tradition of Arthur in Cornwall was ripe at the time. Places in the area today include Arthur's Chair, Arthur's Cups and Saucers, and Merlin's Cave. So the idea of an Arthurian connection to Tintagel was apparently not a new one. Geoffrey also had Celtic tradition to draw on--a tradition that made great importance to the land of Cornwall as a whole. It is tempting to conclude that Geoffrey made it up. And yet ...
Excavations this century have uncovered pottery consist with that found on the Cadbury Castle site, suggesting that Tintagel does indeed have an Arthurian connection based in fact.
