Fogo and neighboring Ilha Brava are the southernmost islands of Cape Verde and at the western end of the Sotavento group. Unlike some of the other islands in the archipelago which were named after saints, Fogo’s name goes back to the volcanic activity of its dominant feature Pico do Fogo, at 2,829 meters the highest elevation of Cape Verde and also its largest volcano. The third Cape Verde island to be settled by Portuguese –there is no indication of human activity before the Portuguese voyages of exploration - the discovery of Fogo is celebrated with horse races and the “Festas do São Filipe” on May 1. Sao Filipe is Fogo’s largest city with 20,000 inhabitants and the fourth-largest of Cape Verde. Sao Filipe lies on the western flank of a giant volcano which in his 9 kilometer wide caldera has the Pico do Fogo, an active stratovolcano which last erupted in 2014-15 and still today emits sulphur vapor through its fumaroles.
