More reliable sources suggest that the ``Santa Cruz'' in actuality refers to the crossroads located in the Meadow of Mudela (so called for its proximity to the pass of Muradal, one of the entrances to the Central Meseta through the Andalusian Plain). On January 30, 1538, Don *lvaro the Elder bought off from Carlos I the towns of Santa Cruz de Mudela and Viso del Puerto (Muradal), under his own terms and along with civil and criminal jurisdiction, for 26,208,626 maraved*es (for comparison, Ferdinand Magellan's epic voyage around the earth, financed by Carlos I in 1518, cost 8,751,125 maravedis).
