Zanzibar Stone Town is the cultural heart of the island and the old city area of Zanzibar City, located on the western shore. The city got its name from the many big multistory buildings made of stone which form the landscape of the old town part. This building is actually not made of stone, but with mortar and corals. Although the corals were a good and easily available building material, they are also easily damageable. Some of the houses are in a bad shape and the Stone Town Conservation Authority co-ordinates the restorations of this houses to maintain the towns original glory.
