Overlooking the Tagus River, in the neighborhood of Belém, the Torre de Belém (also known as the Tower of St. Vincent) is one of the most iconic monuments in Lisbon, built between 1514 and 1520 by order of King Manuel I. Designed by the architect Francisco de Arruda, it is an imposing example of Manueline architecture, the Portuguese Gothic style richly decorated with nautical and ornamental elements (twisted ropes, armillary spheres, crosses of the Order of Christ).

The structure consists of a hexagonal bulwark, designed to house artillery, and a four-story tower approximately 30 meters high, which served as a residence and strategic control point along the river. The southern facade boasts a loggia overlooking the water and the famous rhinoceros-shaped gargoyle, inspired by the first modern rhinoceros to arrive in Europe, a symbol of Portuguese global influence. 

Throughout the centuries, the tower has served various functions: defensive fortress, lighthouse, customs house, and political prison. Since 1983, it has been included in the UNESCO World Heritage List, along with the Jerónimos Monastery, for its historical and architectural value.
