Tintagel Castle perches dramatically on a jagged headland jutting into the Cornish sea, capturing centuries of legend and history. Built by Richard, Earl of Cornwall in the 1230s, the castle's ruins stretch across the rocky promontory with notable features including Merlin's Cave at sea level. The site is famous for its legendary connection to King Arthur, inspired by Geoffrey of Monmouth's 12th-century tale; in reality, Tintagel served as an important stronghold of Cornish rulers from the 5th to 7th centuries. Today, visitors explore the dramatic remains on the headland and mainland, immersed in both the mythic atmosphere and authentic medieval stone architecture overlooking the Celtic seascape.
