The Republic occupies both of the Twin Islands, which form most of its land area. These islands are a part of the Macaronesia region - a large group of several archipelagos in the North Atlantic Ocean. The Ilhos Gêmeos lie Southwest of Madeira, and Northwest of Canary Islands - roughly equidistant between the two. The smaller of the Twin Islands, Refúgia, is to the Northwest, and is home to the capital city (also called Refúgio) - which occupies a large part of the island. The terrain of Refúgia island is predominantly forested, though warm beaches ring the coast, and the rocky Mount Ferreira dominates the Southeast.
