In Madrid, many buildings, similar to the locks, it seems as if you're in a fairy tale. Even city hall affects white spiers and neo-Gothic elements. The architectural tour can start at a huge statue of a bear on the central square of Puerta del Sol. Wander through the intricately decorated royal palace, enjoy the natural beauty of the Retiro Park and then visit one of the many museums of the city. And you can end the day portion of excellent paella and Spanish wine from the Rioja.
