About Sos del Rey Católico

Medieval walls, a castle and stone lanes still ring Sos del Rey Católico on its ridge in the Cinco Villas country of Aragón. Ferdinand the Catholic was born here in 1452, and the palaces and the church of San Esteban show the wealth that followed. The Pyrenees lie to the north, while Zaragoza and Pamplona are both reachable for a longer day out. Spring and autumn are mild and quiet, summer is warm and dry, and winters here are cold with a chance of snow.
