Atalaya de Tormos, standing near the Sotonera reservoir in Huesca province, represents one of the oldest preserved fortifications from Sancho Ramírez's reign in Aragon. This early watchtower, built by Muslims between the late 9th and early 10th centuries, communicated visually with other fortifications such as Torre de San Mitiel and the Castle of Bolea. After Christian conquest in the 11th century, the tower was formally documented in 1091 when Sancho Ramírez ceded it to local lords, later passing to the monastery of San Juan de la Peña in the 12th century. Its remote hilltop location and exceptional preservation make it a significant archaeological site reflecting early medieval frontier defense strategies in northeastern Spain.
