The tower of Belém

  The tower of Belém stands at the mouth of the Tagus River in Lisbon, Portugal. Built in the early 16th century, this UNESCO World Heritage site originally served as a fort to protect the city from maritime invasions and as a ceremonial gateway for explorers returning from their voyages. Its distinct Manueline architecture features intricate stonework, making it a notable historical landmark that draws visitors year-round. In March, the surrounding gardens bloom with local flora, providing a scenic backdrop for photos. Visitors can explore the tower's five stories and enjoy panoramic views of the river and city from the rooftop.
