37 Beautiful Photos of Age-Old City Porto in Portugal

Porto is the second-largest city in Portugal, after Lisbon, and one of the major urban areas in Southern Europe and the capital of the second major great urban area in Portugal. Sometimes called Oporto, it's an age-old city that has one foot firmly in the industrial present. The old town, centered at Ribeira, was built on the hills overlooking the Douro River, and today is a UNESCO World Heritage Site. The 14th-century São Francisco church is a main attraction, as are the local port wine cellars, mostly located across the river at Vila Nova de Gaia.
