New Orleans, Louisiana is a city unlike any other. Combining a rich historic culture of French and Spanish, the French Quarter preserves much of the history and culture that defined the city early in its history. Places like Jackson Square and the Cabildo are some of the oldest European buildings and settlements in the continental United States. Farther up the Mississippi River where town eventually expanded in the 20th century, Audubon Park, named after the famous birder, preserves not only the unique flora of the area, but also an enormous diversity in birds. Many of these birds stay year-round, others migrate in and out with the seasons from as far away as South America.
