The Discoveries Monument, upcloseThis is one of the most emblematic monuments in Lisbon. It generated lots of controversie, along with the Belem Cultural Center, but its imponence and detail soon conquered Lisbon. It has an auditorium inside, with theatre plays and expositions, and you can go all the way to the top and enjoy the view.
