The city is named after the Duke of Orleans, who reigned as Regent for Louis XV from 1715 to 1723, as it was established by French colonists and strongly influenced by their European culture. It is well known for its distinct French and Spanish Creole architecture, as well as its cross-cultural and multilingual heritage. New Orleans is also famous for its cuisine, music (particularly as the birthplace of jazz), and its annual celebrations and festivals, most notably Mardi Gras, dating to French colonial times. The city is often referred to as the «most unique» in the United States.
New Orleans is located in southeastern Louisiana, straddling the Mississippi River. The city and Orleans Parish (French: paroisse d'Orléans) are coterminous. The city and parish are bounded by the parishes of St. Tammany to the north, St. Bernard to the east, Plaquemines to the south, and Jefferson to the south and west. Lake Pontchartrain, part of which is included in the city limits, lies to the north and Lake Borgne lies to the east.
In New Orleans , you'll find the roots of jazz and a blossoming culture that has been long described as being unlike anything else in the United States. Founded in 1718, it is one the nation's oldest cities and has an atmosphere rich with a mix of French sophistication, Creole, African-American, Caribbean, Irish, Haitian, German, and Vietnamese, all creating an energy that can be described as something greater than the sum of its parts. Though hit hard by Hurricane Katrina in 2005, the city continues to rebound, and it remains the largest city in Louisiana and one of the top tourist destinations in the United States.
