"The city of Oporto, built along the hillsides overlooking the mouth of the Douro river, is an outstanding urban landscape with a 2,000-year history. Its continuous growth, linked to the sea (the Romans gave it the name Portus, or port), can be seen in the many and varied monuments, from the cathedral with its Romanesque choir, to the neoclassical Stock Exchange and the typically Portuguese Manueline-style Church of Santa Clara."

Porto or Oporto of Portugal. Thanks to Michael of Luxembourg. Nice stamps used.
The bridge was built in 1886. My first postcard from Portugal. It is one of my first postcard that I swapped through postcrossing. Thanks to "PocketPiglet".
