Shanga, Pate Island
Shanga is an archaeological site located in Pate Island off the Eastern Coast of Africa. The site covers about. Shanga was excavated during an eight-year period in which archaeologists examined Swahili origins. The archaeological evidence in the form of coins, pottery, glass and beads all suggest that a Swahili community inhabited the area during the eighth century. Evidence from the findings also indicates that the site was a Muslim trading community that had networks in Asia.
Location
Shanga is located on Pate Island — part of the Lamu Archipelago in the Indian Ocean. It is near the northern coast of Kenya. Coordinates: 41.04 E 2.08 S.Topography
Pate Island was formed as a result of fossilized coral reefs. Shanga itself is located on the southern part of the island that faces the Indian Ocean. The island is bordered by mangroves on land and by coral reefs on the shore. Mangroves tend to grow along the shore because they require the salt. Overall the island has poor soil and a relatively flat surface which is covered in white sand. The sand often creates dunes that can reach up to about in height. Coconut plantations can be found in abundance in the sandy regions. Horton notes that the only soil suitable for growing crops like sorghum, is the red soil located towards the center of the island. Drinking water was accessed by digging wells into the large sand dunes.History
Based on archaeological evidence, it is known that Shanga was first inhabited by the Swahili in the 8th century. According to Captain Chauncey Hugh Stigand and his version of the Pate Chronicles, the history of Shanga began with the arrival of Sulaiman ibn Sulaiman ibn Muzaffar al-Nabhan in 600 AD. It is stated that Sulaiman married the daughter of the king of Pate, thus giving him authority to rule over part of the island. Shanga was an independent town at the time of this event, so it did not fall under Sulaiman’s jurisdiction. It was Sulaiman’s royal descendants, however, that were eventually responsible for conquering Shanga later on.The Swahili community in Shanga continued to thrive there for 600 years until their disappearance in the early 15th century. Oral traditions claim that the site was deserted circa 1400-1425. Shanga remained abandoned and unnoticed until the early 20th century. Horton mentions that it was Captain Chauncey Stigand who noticed Shanga’s ruins on Pate Island. Stigand, however never made an attempt to look more into them. The first archaeological study in Shanga would not take place until the 1950s with the arrival of Dr. James Kirkman. According to Horton, the Washanga still remain, although they now live in Siyu, a neighboring Swahili town. It is unclear as to why Shanga was abandoned in the early 15th century. Horton speculates that the community could have deserted the area for political reasons although it was more than likely due to a decline in water supply.
Research
Shanga was first excavated by archaeologist Dr. James Kirkman in the 1950s. Soon after, The British Institute in Eastern Africa cleared part of Shanga in 1965. The areas that were cleared out included the Western Mosque and the wells near the Friday Mosque. In the 1970s, the site was visited by Dr. Richard Wilding, who discovered three coins. Dr. T. Wilson from the National Museums of Kenya extracted pottery samples and wrote a report on the fabrics found in Shanga in 1978. By 1980, most of the research conducted on the site was mainly devoted to mapping the area. The site was excavated by Mark Horton between 1985 - 1988.Stratigraphy and Dating
Between the years 1980-1988, a total of ten trenches were excavated at the site.Phases were also used in the excavation process.
In order to create a chronological framework, as well as measure the depth of deposit in the site, several test pits were dug around the north-south and east-west axes. There were thirty-three test pits in total, each one about one-meter square. The test pits gave archeologists an understanding of Shanga’s development and patterns of occupation. Results from the test pits indicate that there was a concentration of occupation towards the center of the site in between two dune ranges. It is believed that the center of occupation was determined by the availability of water resources. The community that occupied Shanga in the past settled in the areas that showed promising water supply.
Dating
Absolute dating in Shanga was achieved through radiocarbon testing and imported pottery. Both methods of dating present dates ranging from the 8th to 15th centuries. A total of thirteen radiocarbon dates have been processed in the site. The radiocarbon dates demonstrate that Shanga was occupied sometime between the 8th and 15th centuries. Horton points out that Shanga pottery dating has been extensively examined by archaeologists Neville Chittick, James Kirkman and Richard Wilding.Findings
There were several discoveries made at Shanga. Among these discoveries are the excavation of the stone town, stone tombs, human remains, the excavation of the Eastern, Western and Friday Mosques, Muslim coinage, pottery, glass, and beads.Stone Town
Building Materials
Horton explains that the stone town of Shanga was built using primarily two types of coral: Porites solida and coral rag. Porites solida is fairly malleable and can easily be shaped into blocks for wall structures..The practice of shaping coral into blocks occurred approximately between 900 - 1100. Coral rag, a lot more dense is not as easily shaped as Porites solida. Yet despite being a bit more difficult to manage, coral rag was more durable and cheaper to acquire. Coral rag was only used as boundary walls at first, but then eventually became a common building material from 1100 onwards. The coral blocks were set in place with mud or a lime mixture that would serve as mortar. The coral surfaces were often smoothed down with a plaster made from the same limethat was used for mortar.Town Layout
The stone town of Shanga consists of 185 houses that date from the 1300s to the 1400s. In addition to these buildings, there are also piles of stone rubble that suggest that about another 35 homes once existed alongside the 185 structures that still stand today. The stone houses are described by Horton as being “densely packed in the southern part of the settlement.” This left little room for open spaces. Between the homes, there are narrow spaces that reveal remnants of streets that run perpendicularly. Horton notes that there are no diagonal streets found on the site.Architecture
The stone houses of the town all share a similar layout.Horton also mentions an interesting point that describes how the walls were first smoothed out before adding the next layer of masonry. Horton points out that this practice is an architectural technique found with mud-brick building in the Near East.
The rooms of each house were of similar heights ranging from 2.5 m to 3.5 m. The floors inside the houses were made of a lime plaster over coral. The doorways came in two styles: flat-topped or pointed. All of the houses were built with wall niches instead of windows. There are also peg holes found in various rooms in each stone house. Horton speculates that the purpose of these peg holes might have been to “support or display cloth hung on the walls."
Tombs
The sheer number of tombs found at Shanga is far greater in comparison to any other site along the East African coast. According to Horton, there are roughly around five hundred stone tombs scattered throughout the site. He speculates that there might be about seventy more tombs hidden underneath the sands. The tombs are mainly found grouped together in one of the three following main areas including: the external cemetery, the Friday Mosque, and in the outskirts of the stone town. The greatest concentration of tombs can be found in the external cemetery.The stone tombs are made up of the same materials used to build the stone houses. The tombs contain both coral rag and lime. Several of these stone tombs include inscriptions written in Arabic. Each stone tomb is unique in its way and comes in a wide range of styles which are classified as ‘types.’ The types of stone tombs found at Shanga include: rubble, rectangular platform, headstone with platform, enclosure with headstone, platform with head insets, small enclosure, large enclosure, complex, and pillar.
The Friday Mosque
The Friday Mosque is the oldest of the three mosques found in Shanga. Horton claims that the Friday Mosque dates back to the 11th century. The other two mosques: the Eastern Mosque and the Western Mosque were not built until the late 13th to 14th centuries. The fact that the mosques exist on the site "is the basis for the claim of a significantly early Islamic presence in Shanga." Horton states that the Friday Mosque underwent several reconstructions and expansions during its time before it was destroyed and abandoned in the fifteenth century.The Friday Mosque found today is in a state of ruin. Yet the current remains have contributed a great deal in understanding the overall layout of the mosque. The main room of the mosque has a rectangular layout with a plaster floor. Unlike the houses from the stone town, the mosques had windows at one point. The Friday mosque also has remnants of a minbar, whose dimensions are roughly around 3.3 x 1.1 m. Outside of the mosque there are courtyards on both East and West ends. The Western courtyard was different from the Eastern courtyard due to the fact that it contained a well. It is believed that the Western courtyard was used as a washing area. Horton also mentions that near the well there is a large triangular space that once served as two rooms. The purpose of these rooms is still unknown.
Excavations at the Friday Mosque reveal a series of seventeen phases underneath. The mosque itself was built over several older structures made of timber and stone. According to radiocarbon testing the first mosque built on the site dates back to the 8th century. The first mosque would then undergo a series of reconstructions in the next 200 years which eventually led to the construction of the Friday Mosque. The earliest radiocarbon date extracted from the mosque belongs to a burnt tree stump, which dates back to 703-848 cal AD. The latest radiocarbon date ranges from 1002-1106 AD, and it was obtained from a carbon layer below the floor of the mosque.
