"Descripcion é historia del castillo de la aljafería" by Mariano Nougués Secall is a historical work written around 1846. Born from Queen Isabella I's visit to the Aljafería Palace in Zaragoza, this detailed study examines the fortress's architecture, Moorish origins, and transformation through centuries. From ancient mosques to royal celebrations, from Inquisition tribunals to imprisoned generals, Nougués chronicles the castle's layered past—documenting inscriptions, royal decrees, and the building's shifting roles under Arab and Christian rule.
