Economy

The island is located with the Kilwa Masoko township authority. The main economic activities on the island are Cultural tourism, fishing and subsistence agriculture. Economic growth is limited due to limited accessibility to the island. The island has no rivers and the main source for water is wells. Many of the island's freshwater wells have been used for over a millennium. The island is served by small boats to and from the port at Kilwa Masoko. The island's only electricity is solar based and low capacity. There are no roads on the island thus most transport is on foot or by motorcycle. To protect the historic integrity of the Island, non-island residents are strictly prohibited from visiting the island without a visitor's permit from the tourist information center in downtown Kilwa Masoko. Much of the historical artifacts and buildings on the island are yet to be unearthed.

from the mainland from at least the 8th century CE and eventually became one of the most powerful Swahili settlements along the East African coast. Historically, it was the center of the Kilwa Sultanate, a medieval Swahili sultanate whose authority at its height in the 13th-15th centuries stretched the entire length of the Swahili Coast. The seasonal wind reversals would affect trade circulations. In 1331CE, Moroccan traveller and scholar Ibn Battuta visited Kilwa and described it as one of the beautiful cities of the world. Trade connections with the Arabian Peninsula as well as India and China influenced the growth and development of Kilwa, and, though there are Islamic words and customs that have been adapted to the culture, the origins are African. Many of the Swahili settlements showed complex layouts that reflected social relations between groups, however at Kilwa, there are many questions still left unanswered about the town's layout after the Portuguese burnt it to the ground in July 1505. The Swahili cemeteries are located on the edge of the town, which is common for the Swahili region, and large, open spaces were likely used for social gatherings. An important city for trade, around the 13th century there were increased fortifications and a greater flow of goods. For these to take place, there would need to be a form of political administration overseeing the city, controlling the movement of goods. Much of the trade network was with the Arabian peninsula. Kilwa Kisiwani reached its highest point in wealth and commerce between the 13th and 15th centuries CE. Evidence of growth in wealth can be seen with the appearance of stone buildings around the 13th century CE, before which all of the buildings were

. The socio-economic status of the individuals residing there can be inferred from the type of structure they were living in. Among Kilwa's trade exports were spices, tortoiseshell, coconut oil, ivory, and aromatic gums, as well as gold. At around this time, Kilwa had seized control of the trade of gold at

. The wealthier residents of Kilwa owned exotic textiles and foreign ceramics, though items such as luxury clothes are not preserved in the archaeological record. For approximately 500 years, Kilwa minted its own coins. This lasted from about 1100-1600 CE and the coins have been found across the region, including Great Zimbabwe. Marine resources were abundant and used for food, supplemented by the surrounding land. Due to the impact the sea had on Kilwa, including marine resources and trade opportunities, the archaeological investigation of the harbors and ports is considered to be of high importance. The topsoil that covers the limestone at Kilwa was of poor quality, and so food sources on land came from the areas of higher ground. However, the soil in the Kilwa region would have been suitable for growing cotton, which could be used in sail manufacturing. 12th century spindle whorls have been found, indicating that cotton was used and processed in this area.


Ceramics

At first, most of the focus was placed on the archaeology of Kilwa's ports and harbors, however, more and more emphasis is being placed on Kilwa's hinterlands. Ceramic artifacts are plentiful at the site and can be divided into two groups: regional and coastal. All of the ceramics with regional distribution were locally produced, but the area of distribution is limited. These unglazed ceramics were referred to as Kitchen Wares, though their uses were not necessarily just as cooking vessels. All of the varieties of locally produced pottery found in the region were also uncovered at the site of Kilwa itself. While the Kitchen Wares could be seen throughout the region, there were ceramics that were mostly seen within Kilwa itself. These included modeled forms and red-burnished wares. The distribution pattern of the red-burnished wares was coastal. Other ceramic types that were seemingly restricted to town were the imported ceramic vessels from the Arabian peninsula and China. Imported ceramic materials are not found in rural areas. They were used as a sign of social status by the elite. They were kept in wall niches made just for the purpose of displaying them. These imported ceramics played important symbolic roles along the Swahili Coast. The symbolism attached to the imported ceramics was so strong that it carried on to modern

. The lack of imported goods in the hinterlands indicates that, while Kilwa was undergoing a process of urbanization, the other local communities did not undergo a dramatic transformation.


Preservation of the site

In 2004, Kilwa Kisiwani was inscribed on UNESCO's
List of World Heritage in Danger The List of World Heritage in Danger is compiled by the United Nations Educational, Scientific and Cultural Organization (UNESCO) through the World Heritage Committee according to Article 11.4 of the World Heritage Convention,Full title: ''Conv ...
. There is a serious rapid deterioration of the archaeological and monumental heritage of these two islands due to various agents like erosion and vegetation. The eastern section of the Palace of Husuni Kubwa, for example, is progressively disappearing. The damage to the soil caused by rainwater wash is accentuating the risks of the collapse of the remaining structures on the edge of the cliff. The vegetation that proliferates on the cliff has limited the progression of the rain-wash effect but causes the break-up of the masonry structures. The

but later replaced by timber. The structure was entirely roofed, and was perhaps one of the first mosques in the area to have been built without a courtyard. In the early fourteenth century, Sultan al-Hasan ibn Sulaiman, who also built the nearby Palace of Husuni Kubwa, added a southern extension which included a great dome. This dome was described by Ibn Battuta after he visited Kilwa in 1331. You can view a 3D model of the Great Mosqu

Palace of Husuni Kubwa

to grow which is one of the ways the breakwater can be spotted from a distance. Some parts of the causeway are made from the bedrock, but usually the bedrock was used as a base. Coral stone was used to build up the causeways with sand and lime being used to cement the cobbles together. Some of the stones were left loose. The Palace of Husuni Kubwa is another prominent structure in Kilwa. The majority of the palace was erected in the 14th century by Sultan al-Hasan ibn Sulaiman, who also built an extension to the nearby Great Mosque of Kilwa, although portions may date back to the 13th century. for unknown reasons, the palace was inhabited only for a brief period of time, and abandoned before its completion. In true Swahili architecture style the structure was built out of

. It consists of three major elements: a south court, used primarily for commerce; a residential complex including over one hundred individual rooms; and a wide stairway leading down to a mosque on the beach. Other notable features include a pavilion, which likely served as a reception hall, and an octagonal swimming pool. All of Husuni Kubwa spans across approximately two acres. The coral rag was set in limestone mortar and cut stone was used for decorative pieces, door jams, and vaults. The rooms were about 3 meters tall. The roof was made from cut limestone blocks laid across cut timbers and the floors were white plaster. The main entrance to Husuni Kubwa is from the shore. Most of the imported glazed pottery recovered at the site was Chinese celadon, though there were a few Ying Ch'ing stoneware sherds present, and a Yuan dynasty flask dated to about 1300 CE. Neither the '' Kilwa Chronicle'' nor any other Portuguese accounts describe a building comparable to Husuni Kubwa.


Husuni Ndogo

Husuni Ndogo ("Little Palace") is built from coral rubble and limestone mortar. The rectangular enclosure wall surrounds the complex and at each corner stands a tower. The foundations extend two meters below ground level. It appears to have been built as a fort, but the exact purposes and uses are somewhat unknown. There is some evidence that it, for at least a time, was used as a mosque. Architecturally, it appears to be different from other buildings along the coast, resembling buildings constructed under the Caliphs of the Umayyad at around 661-750 CE. However, whether or not the structure is related or even dates to the Arabic buildings remains uncertain, though it seems unlikely.


Gereza Fort

The Gereza Fort (also called the Arab Fort) is situated between the Makutani Palace and the Great Mosque. There are some evidence that the original structure was Portuguese, while the present form of the fort is of typical Omani forts. The word Gereza means prison in Swahili, possibly indicating the use of the fort as an Omani slave holding building during the late 18th century to late 19th century after the collapse of the Swahili civilization after the arrival of the Portuguese in late 16th century.


Controversies

A lot of Kilwa's history has been written and politicized by Omani and European colonial administrators in the 19th century to justify the occupation and domination of East Africans over the centuries. This view assumes that cultural innovation and historical development in Africa can only come from outside. Hence there has been a lot of contradictory evidence on the origins and the role of foreign immigrants in Kilwa's history.

Though he was credited with the founding, he had arrived at an already inhabited area. He did, however, come to power and is credited with fortifying the city and increasing trade. Tradition also relates that it was the child of this union who founded the Kilwa Sultanate. Archaeological and

Because of trade, some of the people who lived in Kilwa had a higher standard of living, but many others were poor.

took control of the island after besieging it. It remained in Portuguese hands until 1512, when an Arab mercenary captured Kilwa after the Portuguese abandoned their outpost . The city regained some of its earlier prosperity, but in 1784 was conquered by the Omani rulers of Zanzibar. After the Omani conquest, the French built and manned a fort at the northern tip of the island, but the city itself was abandoned in the 1840s. It was later part of the colony of German East Africa from 1886 to 1918.


Health & Education

Since the resident island population is less than 1000 people, there is one school, The Lyahi Koranic Middle school. Older students move to the mainland for further education. There are no healthcare facilities on the Island so residents have to take the boat to the mainland to receive healthcare services at either the Masoka Urban Health Center ot the Masoko BAKWATA Dispensary both located in Kilwa Masoko town.
