The Aljaferia Palace is a fortified palace in Zaragoza, Spain. It was built in the 11th century during the Taifa of Zaragoza period, and served as the residence of the Banu Hud dynasty, the ruling family of the Taifa of Zaragoza. It is considered one of the most important examples of Islamic architecture in Spain, and it has been declared a UNESCO World Heritage Site as part of the Mudéjar Architecture of Aragon.

The palace features a mix of Islamic and Christian architectural styles, with many of the original Moorish decorations having been preserved. Some of the highlights of the palace include the Court of Santa Isabel, the Palace Chapel, and the Throne Room. In the 15th century, the palace was renovated and expanded by the Catholic Monarchs, who used it as a residence during their visits to Zaragoza. The Aljaferia Palace has also been used as a military academy and a prison over the centuries.

Today, the palace is open to the public as a museum, offering visitors a glimpse into the rich history and architecture of Zaragoza and the surrounding region.
