Ponta do Chão de Mangrade
Ponta do Chão de Mangrade 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 west of this point.
