On the Swahili Coast in southern Tanzania lie the ruins of a stone town known as Songo Mnara. The stone town was occupied from the 14th to 16th centuries. Songo Mnara has been recognized at a UNESCO World Heritage Site, along with nearby stone town Kilwa Kisiwani.[2] In total, archaeologists have found six mosques, four cemeteries, and two dozen house blocks along with three enclosed open spaces on the island.[3] Songo Mnara was constructed from rough-coral and mortar.[4] This stonetown was built as one of many trade towns on the Indian Ocean.[2]
