The historic town centre, the Medina, contains a maze of narrow alleys and ancient buildings but is poorly maintained. The old city centre is similar to but smaller than the old town of Lamu. There are many mosques, notably the Badjanani Mosque or ''Ancienne Mosquée de Vendredi'' (old Friday mosque), which is the oldest mosque in the Medina. It was originally built in 1427, and a minaret was added in 1921. The 300-seat theatre of the Alliance Franco-Comorienne serves as a venue for national and international performances, ceremonies, conferences, film screenings, and seminars. Other venues include the 700-seat Al-Kamar, the 500-seat Palais du Peuple, and the 300-seat Foyer des Jeunes de Foumbouni.
