Torre de Belém By the River Tejo

The Belém Tower was the first Portuguese fortification with two floors of firing positions, marking a new evolution in military architecture. The corners of this platform, as well as the top of the tower, are equipped with watchtowers topped with domes reminiscent of Moorish art. The base of the watchtowers features images of wild animals, including a rhinoceros which is considered the first sculpture of this animal in Western European art.
