Santa Justa Elevator - This is sort of an icon of Lisbon. It was completed in 1902 and was originally steam powered. Though it may be reminiscent of something designed by Gustave Eiffel, it was actually designed by an apprentice of his, Raul Mesnier de Ponsard. It was basically built to 'get up the hill'. There's a walkway that extends back from the top of the elvator to the higher neighborhood behind.
