The heart of monumental Manueline Lisbon, Belém overlooks the Tagus, and is now home to the Belém Cultural Centre. This is a pleasant, airy district with villas and gardens, set on a hillside dominating the river. It has strong links with Portuguese maritime history since it was from here in the 15C that ships set out to brave the oceans in search of unknown lands. The Belém Tower, the Monastery of the Hieronymites and the principal museums are located in this district.
