Elevador de Santa Justa
The Santa Justa Elevator is one of Lisbon's more extraordinary structures. Designed by Raoul Mesnier du Ponsard, who studied under French engineer Gustave Eiffel, the Gothic-style tower was built in 1902. Queues are often frustratingly long in high season, but it's an enjoyable ride up to the top. The return ticket sold on board includes access to a high walkway and an even higher miradouro (though this viewing platform is currently closed), but it's a poor value—a 24-hour public transportation pass costs around €7 loaded onto a €0.50 Viagem card and is valid on the elevator as well as all of the city's buses, trams, and metro lines. To skip the queues and the fare, you can access the upper walkway from Largo do Carmo.
