Tlemcen’s Grand Mosque is one of North Africa’s most important Islamic buildings. Begun by the Almoravid leader Youssef ben Tachfine around 1091, it has been substantially rebuilt several times over the centuries but retains some important early features, including the mihrab, elaborately decorated in stucco and carved stone, and a fine cupola with a massive chandelier. More impressive, however, is the atmosphere of reverence that fills the building.

There are 133 steps to the top of the minaret, the oldest in this part of the Maghreb and the highest in town. To visit the mosque, you must dress conservatively.
