Castle-Palace of Mesones de Isuela Monument · Mesones de Isuela, Aranda, Zaragoza Image of Mesones de Isuela, not of the place itself. Castle-palace standing atop a rocky hill above Mesones de Isuela (Aranda, Zaragoza), built from the 12th century and rebuilt in its present form in the 14th century by the archbishop of Zaragoza Lope Fernández de Luna. It belonged earlier to the Templars, who held it from 1175, and later passed to the House of Luna and, after 1382, to the Ximénez de Urrea family. Rectangular in plan, its perimeter is marked by six limestone towers; it preserves two inner courtyards, a chapel with ribbed vaults, the Sala Mayor with round arches, and several residential rooms of palatial character, though it is now partly in ruins. It was declared a Monumento Nacional (a former Spanish national heritage designation, predecessor of the BIC) in 1931. Photo: Diego Delso (CC BY-SA 4.0) What to see and do in Mesones de Isuela
