Belém Tower is a iconic 16th-century fortress in Lisbon, Portugal, symbolizing the country’s Age of Discoveries. Built between 1514 and 1520, it served as a defensive structure on the Tagus River.
 
King Manuel I commissioned the tower, designed by architect Francisco de Arruda, to guard Lisbon’s harbor from invasions and control maritime traffic. It was originally called the Tower of Saint Vincent and linked to Vasco da Gama’s expeditions, later becoming a customs point and lighthouse. This Manueline-style masterpiece blends late Gothic elements with Renaissance and Moorish influences, featuring ornate carvings of ropes, shields, and exotic motifs on lioz limestone. The structure includes a four-story hexagonal tower atop a bastion armed with cannons, plus a grand loggia balcony for royal ceremonies.
 
Inscribed as a UNESCO World Heritage Site in 1983 alongside Jerónimos Monastery, it remains a national emblem
