The ‘Old Towns of Djenne’ is in UNESCO’s World Heritage Site list since 1988. It is one of 855 properties enlisted by the Organization till now. The Great Mosque of Djenne is the largest mud brick building on Earth and one of Mali’s most visited tourists places.
According to UNESCO, the City is inhabited since 250 B.C. and in 15th and 16th centuries it was one of the centres for preaching Islam in the region.
However as the Great Mosque of Djenne is built from mud, so cracks (‘mud-cracks’) occur due to temperature and humidity changes and the mud is eroded by rain as well. Therefore the mosque goes through renovation each year. And that’s a great festival for the people of Djenne.
