Riwa Fort

The Riwa Fort (also Fort), locally known as Kala Qilla or Black Fort, is a fort in central Mumbai (Bombay), India on the banks of the Mithi River. The fort is currently in a dilapidated condition amidst the Dharavi slums. Dharavi was initially a large piece of marshy land that was located strategically, dividing the lands ruled by the British and the Portuguese. John Horne, the then Governor of Bombay, had commissioned the construction of this fort to protect Bombay from the aggressive sea-faring Maratha leader Kanhoji Angre. The Riwa Fort was later captured by the Marathas. The fort falls under the jurisdiction of the Maharashtra Directorate of Archaeology and Museums.
