Luís I Bridge

 It was conceived by the German engineer Théophile Seyrig who cofounded the Eiffel Company.

The bridge crosses the steep, rocky banks of the Douro and rises to almost 45 metres.

There’s a bird’s eye view of the Cais da Ribeira from the top level, which is also used by Porto’s light railway.

After that you could board the Funicular dos Guindais to get down to the waterside.

And if you still haven’t seen enough, cross on the lower deck for pedestrians and local road traffic.
