Final answer:
The tradition of rammed earth mosques is associated with West Africa, particularly in Mali. Cities like Djenné and Timbuktu are famous for their historical mosques built using this technique, with Djenné's Great Mosque recognized as a UNESCO World Heritage site.
Step-by-step explanation:
The tradition of rammed earth mosques is most prominently associated with the region of West Africa, particularly in Mali. The city of Djenné is renowned for its Great Mosque, which exemplifies the use of rammed earth construction. This mosque is part of a historical tradition where local residents contribute to the upkeep by annually applying a new layer of mud. This practice not only involves the community in maintenance but also is believed to have religious significance for those who participate.
Timbuktu is another city in Mali famous for its rammed earth architecture, which includes the historically significant Sankore Mosque, a center of Islamic learning and a striking example of the unique architectural style of Sudanese West Africa. These earthen structures are not only of cultural and religious importance but have also attracted the attention of UNESCO, leading to the designation of Djenné as a World Heritage site in 1988. While this recognition helps preserve these significant sites, it also imposes restrictions on local residents regarding modernization of their homes.
