The Grand Mosque is the visual and spiritual centre of Bondoukou's old quarter. It is one of the oldest mosques in Côte d'Ivoire and a rare surviving example of the West African Sudano-Sahelian mud-brick architecture this far south — most surviving examples are in Mali, Burkina Faso, and northern Ghana.
Non-Muslims usually cannot enter, but the exterior — particularly the pyramid-shaped minaret — is worth a slow walk around. The surrounding lanes of the Dyula quarter, with their mud-walled compounds and Quranic schools, are among the most atmospheric corners of town.
