Castillo-Palacio de Cetina represents a remarkable fusion of military fortress and aristocratic residence in the Zaragoza province town of Cetina. Constructed in the late 13th century by King Pedro III of Aragón as a frontier defensive structure against Castilian incursion, it was transformed by Mosén González de Liñán in 1410 into a palatial residence with expanded towers and enhanced amenities. The structure features distinctive Mudejar architectural elements with two end towers—the eastern tower preserving its original 13th-century defensive character while the western tower reflects 15th-century residential refinement. The castle gained cultural prestige when writer Francisco de Quevedo was married in its chapel in 1634, though it now stands partially abandoned despite ongoing private residential use.
