The ubiquitous influence of Swahili architecture
The African continent has, throughout history, been a major player in the ever-evolving history of human migration. As a result of this population movement, cultures and customs have been shared, adapted and reinvented, and architectural styles are no exception. In a way, the diverse architecture in Africa is a lens to look at to understand the intricacies of migration. There are ancient indigenous and building typologies on the continent that have emerged from the organic assimilation of cultures. There are also remnants of colonial architecture, a legacy not of voluntary migration but of forced colonial imposition.
However, there is a part of the continent that is home to a uniquely rich architectural tradition – the Swahili Coast. A narrow strip of land stretching along the eastern edge of Africa from Mozambique in the south to Somalia in the north is home to so-called Swahili architecture, an architectural representation of a cultural combination of influences from mainland Africa to the Arabian Peninsula and South Asia.
The basis of this Swahili culture can be found in a loose amalgamation of old city-states on the Swahili coast – Lamu, Zanzibar and Kilwa, all of which have been declared UNESCO World Heritage Sites. In the 13th century the states existed as Commercial centers with the golden kingdom of Great Zimbabwe in the deeper interior of the continent. The ivory and food trade made the city-states prosperous – but that wealth was also borne by the dark undercurrent of the slave trade in the Indian Ocean.
A balancing act: How architecture tourism can become more sustainable
A defining element of Swahili architecture is the widespread use of limestone, which gives the streetscapes of Lamu Old Town in Kenya and Stone Town in Zanzibar their distinctive appearance. The Coral stone is built into masonry with a mortar made of lime, sand and red earth, which protects the interior from the coastal heat. Mangrove stakes found on site were used to build the roofs, an example of the defining feature of Swahili architecture – that of a style that is a distinctive amalgamation of cultural influences.
In contrast to the smooth, white-colored exterior walls of buildings on the Swahili coast, the one is rich in detail Decorating doors is also a central element that expresses the Swahili architecture. The designs of the intricately carved wooden doors go back to a long tradition of craftsmen from the Swahili coast – who in turn saw influences from the Middle East and the Indian subcontinent. Doors with rectangular frames and straight lintels are emblematic of an older Swahili style, with arched lintels not becoming more common until the late 19th century, with greater Middle Eastern influence. There were carved Arabic inscriptions in the lintel – mostly either a quote from the Koran or information about the respective homeowner.
At the urban level, Swahili cities are divided into districts separated by city walls, with religion playing an important role in urban planning. A neighborhood mosque was the center of every community, with every city also hosting Friday mosques. A standard Islamic plan was the basis of this design, with a large central mosque and main roads running north, south, east and west from its surroundings. These streets are characteristically narrow, a defining urban feature of Stone Town and the old town of Lamu.
Inside, the typical Swahili house was designed around a self-contained central courtyard. The living room is separated from the public space and an inner porch is based on an empty wall that blocks the view of the inner courtyard. Wooden shutters be present, half open to daylight, together with artfully sweeping balconies and concrete benches attached to the main building facade. The inner courtyard, which is not visible to the public, serves to cool down the internal structure and at the same time serves as a key element for maintaining privacy.
Throughout history, Swahili architecture has evolved in connection with migrants who settled on the Swahili coast. The relatively young, UNESCO-protected status of Kilwa, Lamu and Stone Town has the emergence of local design guides – like such one for Stone Town outlines the harmonious methods for working with the historical stone architecture. There were also firms like Urko Sanchez Architects with projects in the old town of Lamu – buildings in a modern style that pays homage to the principles of Swahili architecture.
The influence of Swahili architecture is widespread – and a look at its architecture shows the lasting ability of the building methods passed down through generations and how human migration acts as a catalyst not only for cultural exchange, but also for changing the way of building .
