A 16th-century fortified tower on the Tagus River that served as a point of embarkation for Portuguese explorers and a ceremonial gateway to Lisbon. Built in the Portuguese Manueline style with Moorish architectural influences, it symbolizes Portugal's maritime power during the Age of Discoveries. Now a UNESCO World Heritage Site, visitors can explore the 30-metre limestone structure with its bastion and four-storey tower that once guarded the river's entrance.
