The tiles on the buildings drew me to them.
It may be the second largest city in Portugal and also second to Lisbon in terms of fame but Porto surely deserves equal billing for its beauty and culture and as an entrance way to the wonderful Douro valley.
The city was recognized as a World Heritage Site by UNESCO in 1996. It is reputed to be city from which Portugal got its name and is definitely the city from which Port wine got its name.
For me it is the beautiful waterfront along the Douro river, the winding streets and the tiles on the houses and public buildings that make the city so amazing.
View of a narrow side street. As I walked along this street there was opera music wafting out of an upper window. I cannot capture the whole feeling for you but I hope I've given you some idea.
And along the Douro valley there are many opportunities to enjoy very fine Port.
