World's Most Beautiful Train Stations

São Bento Station, Porto, Portugal

While the exterior is certainly beautiful—and brings to mind 19th-century Parisian architecture with its mansard roof and stone façade—it is the front hall that will make you gasp. The walls are covered with 20,000 splendid azulejo tin-glazed ceramic tiles, which took 11 years for artist Jorge Colaço to complete.

How to See It: Zero in on the blue and white tile panels, which depict the history of transportation as well as historic battles and artistic renderings of 14th-century King João I and Queen Philippa of Lancaster by the city’s cathedral.
