Standing on the waterfront at Belem near the mouth of the River Tagus is the Torre de Belém, arguably the most iconic symbol of Lisbon.
Originally conceived as a lighthouse, the tower was eventually built as a defensive fortress on the orders of King Manuel I.
Granted World Heritage status by UNESCO in 1983, the Belém Tower is today one of the most popular sightseeing attractions in Lisbon.
Reached by a narrow walkway from Belem's broad esplanade, this quirky Manueline gem is a delight to explore.
