Card #5, A Delicious Sip of Porto

This lovely card hails from Porto, Portugal, known for its production of its own lovely variety of dessert wine. Of the Wikipedia articles I've read so far, Porto seems to be the most fascinating city I've heard from so far. The structures on this card are the Clerigos Tower and St. Bento's Station (which is sadly unrepresented on Wikipedia). Porto has had a long and storied history through its combination of being a major shipping port and being on the Iberian peninsula, which has undergone many major cultural transformations in its history. The city is also known for its cuisine, and its city center has been named a UNESCO World Heritage Site, a very well-respected designation. This card comes from user blu, arriving on September 12 after 10 days of travel.
