Dubuque, Iowa, United States

One of Iowa’s few cities laid out among rolling bluffs, Dubuque is called the “Masterpiece on the Mississippi” for its 19th-century ingenuity and modern-day cultural evolution. Timber and boatbuilding were central to the city’s growth, with wood harvested in Minnesota and Wisconsin. The spirit of this river town lives on in the Cathedral Historic District, dotted with well-preserved buildings and authentic period lampposts. Today, the city is praised for its livability and for its riverside developments, including a museum and aquarium dedicated to the Mississippi River.
