These pretty buildings along the Douro are in Porto, Portugal. The Douro is the river that divides Porto from Villa Nova de Gaia. Up this river you will find the Alto Douro region, a UNESCO World Heritage site, famous for wine growing. In the past, wine was transported down the river and stored in cellars just across the river from these buildings. Porto is also famous for a particular type of wine. (Take a wild guess.)
Yep. Port wine!
FUN FACT: For Harry Potter fanatics like me, Porto also served as major inspiration for the magical novels. Author, J.K. Rowling moved to Porto shortly after her mother’s death in the early 1990’s to work as an English teacher. It is here that she brought the still-growing manuscript for Harry Potter and wrote part of the first book. There is even a famous bookshop in Porto that inspired the library at Hogwarts.
