Great Mosque of Qal'at Bani Hammad

The Great Mosque of Al Qala'a (Masjid El Qala'a) is a former Sunni mosque, now in partial ruins, located in the UNESCO World Heritage city of Qal'at Bani Hammad, in the province of M'sila, Algeria. Its construction dates from the early 11th century, during the rule of the Hammadid Emir Hammad ibn Buluggin. The mosque spans an area of over 3,500 square metres (38, 000 sq ft), taking on a rectangular layout. It encompasses a vast sahn, a hypostyle prayer hall, and a square 25-metre-tall (82 ft) minaret. Regarded as one of the largest historic mosques in Algeria, second only to the Mansourah, it also contains one of the country's oldest minarets. Additionally, the mosque likely exerted an influence on subsequent Almohad minarets, notably the Giralda in Seville. Together with other archaeological remnants of palatial structures, it stands as a primary testament to the opulence and impact of the Hammadid civilization.
