An early Swahili trading settlement on the southwest coast of Unguja Island (Zanzibar), among the oldest urban/proto-urban Indian Ocean trade sites on the East African coast; imported pottery from India, the Persian Gulf (Sasanian-Islamic wares), China, and the late Roman Mediterranean attests to long-distance commerce reaching back to the early 6th century, with a mosque ruin marking early Islamic contact by the 8th-9th century.
Declined as a leading emporium after the 8th-10th century peak as other Swahili towns (Kilwa, Mombasa, Manda) rose to prominence in the Indian Ocean trade network; reduced-scale settlement continued at the site for centuries afterward, but its major trading-port role ended.
