The historic ruins of Pomoni on the island of Anjouan are a compelling testament to 19th-century colonial industrial history. Pomoni was the site of a large-scale sugar factory operated in the 1840s and 1850s under the significant influence of British consul William Sunley. At its peak, the facility was one of the most modern in the region, utilizing advanced steam engine technology for sugarcane processing. The ruins comprise factory hall foundations, remnants of boiler houses, and chimneys rising amidst tropical vegetation. This site sheds light on a dark chapter of history, as it is closely linked to the system of indentured labor and the transition from the slave trade to colonial exploitation. Pomoni served as a key export port from which sugar was shipped globally, granting Anjouan temporary economic prominence. Today, the ruins provide a melancholic insight into the rise and fall of industrial ambitions in the Comoros. Archaeologically, they are of great importance for studying the history of technology in the western Indian Ocean.
