Art has been part of Lisbon’s metro stations ever since the first stations in the 1950s, and the Olaias metro station was no exception. Located on the Red Line, built to ease access to the Expo ’98 site, its architecture is like a Modern Art statement, incorporating several art installations. It is often described as the most beautiful of the metro stations in Lisbon, although some might say it is “disconcerting,” like “If you were trapped inside a giant kaleidoscope.” In 2014, The Guardian included it on its list of the 12 most beautiful metro stations in the world.
