What is "aljaferia"

The Aljafería Palace (; , tr. Qasr al-Jaʿfariya) is a fortified medieval Islamic palace built during the second half of the 11th century in the Taifa of Zaragoza of Al-Andalus, present day Zaragoza, Spain. It was the residence of the Banu Hud dynasty during the era of Abu Jaffar Al-Muqtadir after abolishing Banu Tujibi of Kindah dynasty. The palace reflects the splendor attained by the kingdom of the taifa of Zaragoza at the height of its grandeur. The palace currently contains the Cortes (regional parliament) of the autonomous community of Aragon.

The structure holds unique importance in that it is the only conserved testimony of a large building of Spanish Islamic architecture of the era of the Taifas (independent kingdoms).
