Ghana, formerly known as the Gold Coast, was the first African country to the south of the Sahara to gain political independence from colonial rule in 1957. This former British colony of 92,000 square miles (about 238,000 square kilometers) shares boundaries with three French-speaking nations: the Côte d'Ivoire to the west, Burkina Faso to the north, and Togo to the east. The Gulf of Guinea of the Atlantic Ocean is to the south of the country. Because much of the Precambrian rocks systems that composed most of the territories have been worn to almost a plain, the country is generally low in its physical relief. The major highlands of the country include the Kwahu Plateau, which lies in the middle section of the country. Several important rivers flow from the plateau. Located to the eastern sector of the country are the Akuampim-Togo Ranges. The Akuapim Range runs from the west of Accra and ends at the gorge at the Volta River, where the Akosombo Dam on the river has been constructed. The southern end of the Togo Range begins at the Volta Dam and runs along the country's border in a northeasterly direction.
