Stone town: The stone town is a unique architectural and  cultural mix that has formed over a millenia of interaction between people from  the East African mainland, Arabia, the Persian Gulf, India, China, Portugal and  beyond. A guided tour may be organised to take you through the narrow twisting  gullys into the market where you may catch the fish auction.
                      In light of  its historical significance and value, the United Nations has declared it as  one of the World's Cultural Heritage sites. This has further sparked an  architectural restoration effort after many years of neglect.
