Intro: Porto is an adventurous city of hills, rivers, bridges, old town pavements, many churches some with decorated with magnificent exterior blue and white tiles; it’s a city that makes port wine, of course. There is a medieval Ribeira (riverside) district with narrow cobbled streets that wind past old merchants’ houses and plenty of cafes.  The city is the second largest in Portugal and is home to a fine university founded in 1911 that focuses on science & medicine.
