Belém Tower, Portugal

Belém Tower is a fortified tower located in the Belém district of Lisbon, Portugal.
It was built in the early 16th century in the Portuguese late Gothic style, the Manueline, to commemorate Vasco da Gama's expedition. This defensive, yet elegant construction has become one of the symbols of the city, a memorial to the Portuguese power during the Age of the Great Discoveries. In 1983 it was classified, together with the nearby Mosteiro dos Jerónimos, as a UNESCO World Heritage Site.
