Go to the Tower of Belem, also known as Belém Tower, and officially as the Tower of Saint Vincent. It’s a 16th-century fort on the Tagus riverbanks that served as a loading dock for Portuguese explorers. Built during the height of the Portuguese Renaissance, it is a prominent example of the Portuguese Manueline style, incorporating hints of other architectural styles.

The tower was built from lioz limestone (also known as, pedra lioz, Royal Stone (pedra real), it’s a type of limestone that originated in Lisbon. Famed for its use as an ornamental stone, its use was prolific in palaces, cathedrals, and important civic buildings throughout the former Portuguese Empire. Owing to its historical relevance, it was designated a Global Heritage Stone Resource), and is a bastion and a 30-meter, four-story tower. It was designated a UNESCO World Heritage Site in 1983. It was built on a small island in the Tagus river near the Lisbon shore.

It’s full of history, beautiful on a sunny day, it looks great on Instagram, and the sunsets are amazing. Oh, and it’s obviously on the water, which is really nice for those fresh breezes on a hot Lisbon summer day.
