City of Oporto seen from the south bank of the Douro River . In the image you can see the Ribeira do Porto, the most iconic area of the city, and the Torre dos Clérigos, ex-libris of the city.

The boats in the foreground are the "Rabelos" boats, boats that remind us of the history of Port Wine, where the wine was transported downstream from the Douro to its Cellars in Vila Nova de Gaia.
