What is "kelin"

Kelin was an ancient Iberian city located on the hill of Los Villares ( Caudete de las Fuentes, Valencia). The site was inhabited from the Proto-Iberian period (7th century BC) to the Late Iberian period (2nd to 1st centuries BC). The site was walled and covered around 10 hectares. The archaeological site has been known from the mid-18th century, although it was first excavated archaeologically in 1956, with later campaigns as recent as 2011.
