Archaeologists have been analyzing the layout of stone towns on the Swahili coast, mainly focusing on the relationship of the mosques and houses, in order to understand the role of the Swahili coast in Islamic culture, the functions of specific towns, and the complex economic and ritual process of land ownership. Open spaces in towns were used for both functional purposes for social organization. Cemeteries are found both inside and outside the town walls. The layout of Songo Mnara is typical of stone towns along the Swahili coast, though its wall is a unique feature.
