The Great Mosque of Béjaïa, also known as the Al-Mansuriyah Mosque, was one of the major Islamic monuments of medieval North Africa, built during the period when Béjaïa was the capital of the Hammadid dynasty in the 11th and 12th centuries. The Hammadids made Béjaïa a cultural and commercial centre of the western Mediterranean, and the mosque was central to that civic life.
The original structure was substantially altered through the Ottoman and French colonial periods, and what survives is a complex palimpsest of different eras rather than a pristine medieval building. Nevertheless, the site is historically significant and worth visiting for anyone interested in the medieval Islamic world of North Africa. The location in the old town makes it easy to combine with a walk through the historic streets.
