After the abolition of slavery in 1897, the industry literally went underground and the Mangapwani Caves stand testament to this with a natural cave and a man-made cavern on site used for the incarceration of slaves. The slaves were kept here until they were secretly transported to cargo ships and delivered to slave markets across Europe and the Indian subcontinent. The first is a large natural cave with a freshwater pool and the man-made cavern is a dank, dark cell with few air vents protruding above ground. After 50 slaves were forced inside, poles were fitted into gouges above their heads and planks were laid down so that another 50 men could be crammed in on top. To gain some insight into the unspeakable living conditions of slaves in the 1800s in east Africa, it's best to make a turn at Mangapwani.
Address: The caves are located 12 miles (20km) north of Stone Town
