Alonso de Cárdenas

Alonso de Cárdenas was a Spanish noble who was the 44th and 47th (and last) Grand Master of the Order of Santiago before the title passed to the Catholic Monarchs as the need for a powerful military order outside the direct control of the king ceased to exist with the end of the Reconquista. He is famous for building the castle at Puebla del Maestre in 1483. He was the father of García López de Cárdenas. Provided by Wikipedia
