What is Ribeira District known for?
Ribeira is the district that made Porto a UNESCO World Heritage Site. This compact quarter along the north bank of the Douro River has functioned as Porto's commercial heart since medieval times, when merchants loaded barrels of port wine onto flat-bottomed rabelo boats for transport downstream to the Atlantic. The buildings — narrow granite townhouses painted in ochre, terracotta, and blue — stack up the hillside so steeply that some houses can be entered at ground level on one street and from the roof on the street above. Today the riverfront Cais da Ribeira is lined with restaurants and cafés where you can watch the Douro slide by beneath the iron arc of the Dom Luís I Bridge, with the port wine lodges of Vila Nova de Gaia glowing on the opposite bank.
