Stone Town
Stone Town, also known as Mji Mkongwe (Swahili for "old town"), is the old part of Zanzibar City, the main city of Zanzibar, in Tanzania. The newer portion of the city is known as Ng'ambo, Swahili for 'the other side'. Stone Town is located on the western coast of Unguja, the main island of the Zanzibar Archipelago. Former capital of the Zanzibar Sultanate, and flourishing centre of the spice trade as well as the slave trade in the 19th century, it retained its importance as the main city of Zanzibar during the period of the British protectorate. When Tanganyika and Zanzibar joined each other to form the United Republic of Tanzania, Zanzibar kept a semi-autonomous status, with Stone Town as its local government seat.
Jambiani
Jambiani is a group of villages on the Tanzanian island of Unguja, part of Zanzibar. It is located on the southeast coast between Paje and Makunduchi. Jambiani has a strong seaweed culture with many farms dotting the coastline and employing 15,000 locals, mainly women. 
Most seaweed that is farmed here is sold to the Zanea Seaweeds Ltd company and distributed around the globe. The Island of Zanzibar produces around 11,000 tons of seaweed each year, a large amount of this coming from Jambiani sources.
