Tubmanburg, also known as Bomi and formerly known as Vaitown, is the capital of Bomi County in Liberia. It lies in the Bomi Hills northwest of Monrovia and was an iron ore and diamond mining centre until is was largely destroyed in the Liberian Civil War. During the Second Liberian Civil War, it was the headquarters of the Liberians United for Reconciliation and Democracy rebel group. Most residents are members of Vai tribe.
A key attraction is Blue Lake, also known as Bomi Lake. Blue Lake is about 300 feet deep. It is suspended midway between the peaks of the surrounding mountains which, with the sun’s reflection, give the lake its blue hue. The waters spring from a huge pit dug by the Liberia Mining Company, an American-owned company that ceased operations in the country because of the presumed depletion of iron ore in the area.
