Not quite correct Hugo, it is Discoveries Monument (Padrão dos Descobrimentos), built on the north bank of the Tagus River, Lisbon in 1960 to commemorate the 500th anniversary of the death of Prince Henry the Navigator.
Detail of the monument showing the mathematician and cosmographer Pedro Nunes holding an armillary sphere (center). To his left, Jácome de Maiorca (cosmographer and chart maker) and Pedro Escobar (navigator); to his right, Pêro de Alenquer (navigator), Gil Eanes (navigator) and João Gonçalves Zarco (navigator).
It represents a three-sailed ship ready to depart, with sculptures of important historical figures such as King Manuel I carrying an armillary sphere, poet Camões holding verses from The Lusiads, Vasco da Gama, Magellan, Cabral, and several other notable Portuguese explorers, crusaders, monks, cartographers, and cosmographers, following Prince Henry the Navigator at the prow holding a small vessel. The only female is queen Felipa of Lancaster, mother of Henry the navigator, the brain of the discoveries.
Inside is an exhibition space with temporary exhibits, an interesting film about the city of Lisbon, and an elevator that takes visitors to the top for some bird's-eye views of Belem and its monuments.
The pavement in front of the monument is decorated with a mosaic that was offered by the South African government in 1960, representing a compass with the map of the world charting the routes taken by the Portuguese explorers.
Sorry only half a point for that!
