King Arthur. Heroic British warlord who led the fight against marauding Anglo-Saxons, or a figment of a writer's fertile imagination? It's a question that's been puzzling poets, chroniclers, historians and film-makers for more than 1,000 years.
And nowhere does this question have more resonance than on a small, windswept, rain-battered headland projecting into the sea off north Cornwall: Tintagel.
Numerous sites across north-west Europe – from Glastonbury Abbey in Somerset to the Forest of Paimpont in Brittany – have trumpeted their connections to King Arthur. Yet surely none are as intimately linked to the legendary warlord as Tintagel.
