In brief
The island remains are connected to the networks of the Indian Ocean.
Useful to know
Kilwa Kisiwani and Songo Mnara are historic island port centers near present-day Tanzania. Their bloom is associated with trade in the Indian Ocean during the 13th-XVIth century. The findings include objects from various distant regions. [1]
For urban reading, start from the island position and the connection with the sea roads. Buildings are not isolated local history, but they are also not just copies of external samples. The trade item shows contact; the specific architectural influence requires additional evidence. The division of these two questions makes the description of the port city more accurate.
