The Union Station was completed in 1900 and functioned as a passenger terminal until 1979. Listed on the National Register of Historic Places, the landmark building experienced years of neglect until it was converted into an opulent hotel, detailed with wrought iron and Italian marble. Its lobby features a barrel-vaulted, 65-feet-high ceiling enclosed by stained glass. The station looks spectacular from the outside. If you're not staying at the hotel, you can still enjoy the interior while having drinks or dinner at Ergo restaurant, located inside this historic landmark. Check the hotel's facebook page for upcoming events like bartending competitions and live music nights.

It was used to keep political opponents of António de Oliveira Salazar, the right-wing dictator who governed Portugal in the mid-20th century. It is a harrowing, but important visit.
