Greenan Castle is a historic castle located in South Ayrshire, Scotland. It dates back to the sixteenth century, with its origins likely extending even further into history. On the site was a promontory fort which, in the twelfth century, was converted into a motte-and-bailey fortification.
N.L. Goodrich argues that this was the site of the original Camelot, though she also states that “Camelot” was the name given to whatever stronghold Arthur was occupying at the time. She further identifies the site of Greenan Castle with Badon.
