Situated on the Belém riverfront, the Monument to the Discoveries, or Padrão dos Descobrimentos, is an imposing stone monument built in the style of a caravel to commemorate the explorers and heroes of Portugal’s Age of Discovery. Inaugurated in 1960 to celebrate the 500th anniversary of Prince Henry the Navigator’s death, the monument affords stunning views of Belém, Lisbon and the Tagus estuary.
