Tintagel Castle is a medieval fortification located in the village of Tintagel in Cornwall, England. The castle is located on a headland overlooking the Atlantic Ocean and is believed to date back to the 13th century, although there is evidence of earlier fortifications on the site.

The castle is most famously associated with the legendary King Arthur, who is said to have been born in Tintagel. Although there is no concrete evidence to support this claim, the castle has become a popular destination for tourists interested in the Arthurian legends.

The ruins of the castle consist of a series of walls, towers and courtyards, some of which date back to the 12th century. Visitors can explore the castle remains and take in stunning views of the coastline and surrounding countryside. The castle is also home to an exhibition center that provides further information about the history of the site and the legends associated with King Arthur.

Tintagel Castle is managed by English Heritage and is open to the public year-round. Visitors can purchase tickets on site or in advance online. There is a steep climb up to the castle, so visitors are advised to wear comfortable shoes and be prepared for some challenging terrain.
