Ascensor da Gloria (Gloria Funicular), Lisbon

Instead of viewing this as merely a tourist attraction, consider it an extraordinary engineering achievement! Established in 1885 and designated a national historic site in 2002, this renowned Lisbon tram system boasts vintage, partially wooden streetcars that link Restorers Square ("Praça dos Restauradores") at its lower point to Rua de São Pedro de Alcântara at its upper terminus, just a stone's throw from the equally famous lookout point (or "miradouro").

The steep incline covers a distance of about 900 feet or less (270 meters), so a tram journey typically spans about 2-3 minutes, while a descent along the track takes anywhere from 5 to 8 minutes, depending on one's age and physical stamina. Whichever way you choose, whether riding up or down the Glória Slope ("Calçada da Glória"), you'll pass through one of Lisbon's finest showcases of neighborhood graffiti, predominantly on the right side (when going uphill), as this area is officially dedicated to sanctioned street art.

An entertaining mode of public transportation, particularly for those unfamiliar with the charm of funicular trams. There are excellent photo opportunities from the summit, making it an excellent starting point for exploring the Bairro Alto neighborhood as you descend.
