But the historic hillside city itself should not be overlooked. One of the oldest ciities in Europe, its maze of steep and narrow cobbled streets is home to beautiful plazas, chruches, and houses with colourfully tiled facades. Porto is a historic and varied city, from the warren of narrow streets that make up the ancient Ribeira district through to the grand plaza of the Trindade district. The region is famed for the production of Port, which is still stored and matured in the vast cellars.
