Torre de Chaorna in Arcos de Jalón, Soria, rises from a rocky outcrop above the Cueva de la Mora near the Church of San Miguel. This 11th-century tower reflects Muslim architectural design and heritage, originating from the frontier period between Al-Ándalus and Christian kingdoms. The structure features a rectangular floor plan measuring 5 by 6 metres with walls exceeding one metre in thickness, built of solid masonry. Later falling under the control of the Dukes of Medinaceli, the tower underwent comprehensive restoration work completed at considerable expense, ensuring its preservation for future generations as an important reminder of the region's multicultural medieval past.
