The Jenne Mosque is built entirely of clay, topped by a tower-like dome, it rises above the surrounding desert like a 'sandcastle' on the banks of a fantastic yellow river. Built in 1905 on the foundations of an 11th century mosque, it is the world's largest structure made of clay, 100 metres high and 40 metres wide, and one of the finest examples of Sudanese architecture. The only drawback of the mosque is that it tends to "melt" during the rainy season. Djenne is located on the Niger River Delta and is particularly picturesque during the rainy season, when the whole area becomes an island surrounded by the waters of the great river.
