The island of Kilwa Kisiwani was one of the most important sultanates in the “Swahili Coast” trade network, linking East Africa to the Arabic world. For over 300 years, gold and ivory passed out of its ports, while Chinese silk and porcelain flowed in. The 14th-century palace at Husuni Kubwa is just one of many coral stone ruins that dot the island.

Husuni Kubwa was built by Sultan al-Hasan ibn Sulaiman. It had over 100 rooms, an octagonal swimming pool, and a staging area for loading goods onto ships. Husuni Kubwa, along with other elite Kilwa dwellings, was also equipped with indoor plumbing.
