Considered the 4th largest known natural arch in the world, the Aloba Arch is in Chad. It’s 120 metres high and 77 metres wide. The arch, in the Ennedi Range of the Saharan desert, was carved from sandstone over many years of erosion and is the largest natural arch outside of the United States. The Kunta Kinteh Island is on the Gambia River. Formerly known as James Island, it was visited by explorers when they were searching for sea routes to India in the 1800s. It then became popular through the book and series by Alex Haley ‘Roots’. Declared a UNESCO World Heritage Site on 6 February 2011, the island used to be a cultural exchange zone between Africa and Europe.
