Ponta do Chão de Mangrade (also: Ponta de Mangrade, Ponta Oeste) is the westernmost point of the Island of Santo Antão, and also the westernmost point of Cape Verde and all Africa. It is located 5 km northwest of Monte Trigo and 31 km west of Porto Novo, in a very remote area. The 1494 Treaty of Tordesillas divided the newly discovered lands outside Europe between Portugal and Spain along a meridian 370 leagues (2,193 km) west of this point.
