The island was used as a prison for rebellious slaves in the 1860s and also functioned as a coral mine. There are 15 holiday cottages in the northwest of the island as well as a tennis court, swimming pool, and library and the old European Bungalow has been turned into a restaurant named after Mathews. The old prison remains standing, providing shelter for some of the giant tortoises found on the island and the cells can be visited.
Mangapwani is a town on the Tanzanian island of Unguja, the main island of Zanzibar. It is located on the northwest coast, 25 kilometers (16 miles) north of the Zanzibari capital of Stone Town. The shoreline here contains numerous caves, some of which were used for holding slaves during the black-market slave trade of the 1840s. Among the caves is a popular attraction, the Coral Cavern, which is located two kilometers south of the town.
