King Arthur's Hall (opened 1933) is a historic building in Fore Street, Tintagel, Cornwall, England. Built in the early 1930s by Frederick Thomas Glasscock (died 1934), it originally served as the headquarters for a social organization known as the Order of the Fellowship of the Knights of the Round Table. It contains some works of art relating to the Arthurian legend and is now a popular visitor attraction for Arthurian enthusiasts, and has a bookshop devoted to the subject at the front of the building.
