Archangel
Belém Tower, officially the Tower of Saint Vincent is a 16th-century fortification located in Lisbon that served as a point of embarkation and disembarkation for Portuguese explorers and as a ceremonial gateway to Lisbon. This tower symbolizes Portugal's maritime and colonial power in early modern Europe. It was built during the height of the Portuguese Renaissance, and is a prominent example of the Portuguese Manueline style, but it also incorporates other architectural styles, such as the minarets, which are inspired by Moorish architecture. The structure was built from lioz limestone and is composed of a bastion and a 30-metre (100 ft), four-storey tower.
