What was the name of Arthur's court in early Welsh tradition?

In early Welsh tradition, Arthur’s court was called Celliwig.

Celliwig, also spelled Celliwic, is presented as Arthur’s court in the Welsh tale Culhwch and Olwen, preserved in an 11th-century manuscript although its underlying material is older. The story places Celliwig in Cernyw, the Welsh name for Cornwall. Arthur’s porter, Glewlwyd Gafaelfawr, guards the entrance, and Culhwch must overcome strict rules governing access during a feast.

Welsh Triads also associate Celliwig with Arthur’s court, naming Caradog Freichfras as chief elder and Bytwini or Bedwin as chief bishop. The same tradition refers to other Arthurian courts, including Mynyw and Pen Rhionydd, but Celliwig is generally treated as the earliest named location for Arthur’s court.

The answer is often confused with Camelot, the famous court of later medieval romance. Camelot became dominant in French and English storytelling, while Celliwig belongs to an earlier Welsh layer of tradition. Its exact historical location is uncertain, and proposals have included sites in Cornwall, Wales, and elsewhere. Some scholars also interpret the name, often connected with a grove or wooded place, as partly mythical rather than as a securely identifiable settlement.
