Boston, Massachusetts: Beacon Hill's narrow cobblestone alleyways with gas-lit lanterns and Federal-style row houses may remind you that Boston is no longer an English colony. Visitors visiting the North End will have to convince themselves they're not in Italy.
Washington, D.C.: Frenchman Pierre Charles L'Enfant planned the U.S. capital. He envisioned a Paris-like city with tree-lined boulevards, gardens, and monuments. Washington, D.C.
San Francisco, California: World cultures mix in San Francisco. The city's Mediterranean and vaguely Greek vibe, temperate climate, occasional palm trees, hills, distant mountains, and beach location contrast beautifully with Victorian architecture and Spanish culture.
St. Augustine, Florida: The oldest U.S. city is not Boston, New York, Williamsburg, or Jamestown. That honor goes to Spanish-influenced St. Augustine.
Philadelphia, Pennsylvania: Other old city? Philadelphia. Elfreth's Alley, the country's oldest continually inhabited street, is there. There's more than British colonial history: French Second Empire masterwork Magnificent City Hall
New Orleans, Louisiana: New Orleans, founded by the French, ruled by the Spaniards, then returned to the French, may be America's most European city. The French and Spanish influenced its architecture, gastronomy, music, language, and speed of life.
New Ulm, Minnesota: In Minnesota, recognized for its Scandinavian-American population, New Ulm has over 50% German-Americans.
Santa Barbara, California: They call it the "American Riviera," since its beaches resemble coastal France, yet Santa Barbara is colonial Spain. The city's white stucco and red-tiled rooftops, anchored by Old Mission Santa Barbara, may make "Western St. Augustine" better.
