Castillo de Santo Stephano stands on a hilltop dominating San Esteban de Litera in Huesca province, Aragon. Built in the 9th or 10th century, this fortress was a strategic stronghold through the medieval period, changing hands among various noble families including the Templars, the Cabreras, and the Peralta barons. Though only a restored square tower remains today, it retains historical significance as a chapel and bell tower structure, offering insight into the region's complex feudal past and its importance as a defensive point in medieval Aragon.
