Porto is a coastal city in northwestern Portugal, known for its imposing bridges and port production. In the medieval district of Ribeira, the narrow cobblestone streets are lined with merchant houses and cafes. The Iglesia de San Francisco is known for its extravagant baroque interior, with ornate carvings covered in gold. The 19th-century Palácio de Bolsa, formerly a stock exchange, was built to impress would-be European investors.
