A priest outside the massive Grand Mosquée complex in Mali's medieval city of Djénné. The largest mud-brick building in the world, the mosque is reinforced with a sturdy network of internal timbers. Built in 1905, it was modeled on a mosque first erected on the site in the 11th century. Every year, after the rainy season, much of the population helps repair and resurface the mud walls.
