Off the coast of present-day Tanzania, Kilwa Kisiwani and Songo Mnara are testament to centuries of global cultural exchange and maritime wealth. Built from coral stone and shaped by Swahili, Arab, Persian, and Indian influences, the architectural remains of these cities have endured continuous erosion from rising sea levels, wind, and sand. Through powerful visual storytelling and thoughtful local perspectives, this documentary shares the initiatives to preserve these historic mosques and palaces for future generations.
