What is the name of King Arthur's legendary castle?

Camelot is the legendary castle and court associated with King Arthur.

In Arthurian romance, Camelot functions as the center of Arthur’s kingdom and the setting for his court, Queen Guinevere, and the Knights of the Round Table. It represents the idealized world of chivalry, justice, fellowship, and royal order that later collapses through betrayal and civil conflict.

Camelot does not appear in the earliest surviving Arthurian material. The name first emerges in 12th-century French romance, especially in Chrétien de Troyes’s Lancelot, the Knight of the Cart. Later works, including the Lancelot-Grail cycle and Thomas Malory’s Le Morte d’Arthur, helped establish it as Arthur’s famous capital.

Readers often confuse Camelot with Avalon, the island associated with Arthur’s final journey and eventual resting place. Tintagel is instead linked with Arthur’s conception and birth in many traditions, while Caerleon is a real Welsh city that some medieval texts connect with Arthur’s court. No location has been proven to be the historical Camelot; many proposed sites are modern or speculative associations.
