Order of Calatrava
Its name is a reference to the Order of Calatrava, which was originally situated in Calatrava la Vieja, 60 km to the north. In 1217, the Order of Calatrava moved to Calatrava la Nueva. Thus, the original site became known as "Calatrava la Vieja" ("Old Calatrava") and the new site as "Calatrava la Nueva" (“New Calatrava”).
