Ponte 25 de Abril

The 25 de Abril Bridge is Lisbon's iconic suspension bridge spanning the Tagus River, and yes, it looks remarkably like the Golden Gate — an uncanny twin standing over a completely different ocean. It holds the longest central span in Europe at 1.5 miles, runs two levels (cars on top, trains below since 1999), and carries the name of the 1974 Carnation Revolution that ended decades of dictatorship. Catch it at night when it's lit up and towering over the old docks — it's genuinely dramatic.
