There is a fairytale quality to the tree-lined canal streets of Amsterdam. Boutiques, cafes, apartments and hotels may hide behind the facades of the gabled townhouses, but the look of this beautiful old city has not changed much since its 17th-century Golden Age. Some 7,000 historic buildings remain, many of them beautiful merchants' mansions, located along canals that are laid out in five concentric circles, connected by bridges and intriguing small streets. No matter how many times you walk along the canals, they are enchanting to see, even when traffic and whizzing bicycles dispel the Old-World illusion. On a silent Sunday morning or on a summer evening when the old facades are floodlit, the city is magical.
