The main reason tourists visit Oporto is to sample its legendary port wine, processed, blended and aged in the various lodges of the Vila Nova da Gaia district across the river from the city, via the spectacular two-tiered Dom Luis bridge. Visitors can tour the lodges and finish up with a tasting session. The city also has an historic riverside district called Ribeira, which is undergoing restoration and has been classified as a UNESCO World Heritage Site.
