Lisbon's monument to the Age of Discovery. Best admired from outside.
The Torre de Belem is a filigreed limestone fort standing in the Tagus, Lisbon's monument to the Age of Discovery. It's small, ornate and photogenic — and the queue can outlast the visit.
Worth a look — but it's best from the outside; the interior queue rarely justifies itself.
It's a ticketed sight — book online in advance to skip the queue.
Come before 9am or after 5pm to dodge the tour groups, because the interior is tight, with narrow spiral stairs and a one-in-one-out crush at peak.
