For a fascinating look into the workings of the Spanish stock market, visit this impressive building designed by 19th-century architect Enrique María Rapulles. Located in the same small square as the Ritz hotel and just a short walk from the Prado, its neoclassical facade attracts almost as much attention as that of its illustrious neighbors. Visits are made at noon on weekdays, but you must make a prior call to arrange an appointment. You can view the stock exchange floor through a glass partition above and see a small exhibition on the history of the market.
