How did dhow trade influence the architecture of East African coastal cities?

The dhow trade, which utilized seasonal monsoon winds to link East Africa with the Arabian and Persian Gulf ports and India, was a primary driver of architectural development along the Swahili coast. This maritime commerce facilitated the growth of prosperous, stone-built city-states such as Kilwa, Zanzibar, Mombasa, and Lamu.1

The influence of this trade on architecture included:

• Materials and Construction: Coastal settlements transitioned from early wattle-and-daub dwellings to structures built of coral ragstone, often roofed with mangrove poles and finished with lime mortar.12
• Urban Planning: The trade supported the establishment of sophisticated, permanent stone towns, often situated on islands for security.12
• Decorative Elements: The Swahili architectural style, particularly evident in towns like Lamu, features distinct aesthetic details such as fine plasterwork, decorative rows of wall niches, and deeply carved wooden doors.13
• Religious Architecture: The wealth generated by trade enabled the construction of substantial stone mosques, such as the 12th-century mosque at Kizimkazi, which served as focal points for these Islamic trading centers.12
