The Elevador de Santa Glória is a tram that departs from Praca dos Restauradores and in a few minutes it takes you up a very steep alley. It has been a service since 1885 and has been powered by electricity since 1915. The journey is only 200 meters but it is always crowded with tourists and locals who want to spare themselves the trouble of climbing on foot. Worth taking a short ride on this funicular up to a beautiful look-out point the Miradouro (viewpoint) de São Pedro de Alcantara, the best known and most visited viewpoint of Bairro Alto from where one has a panoramic view of downtown Lisbon and across to the castle.
