Mandeville is a small city in St. Tammany Parish, Louisiana, United States. The population was 11,560 at the 2010 census. Mandeville is located on the North Shore of Lake Pontchartrain, south of Interstate 12. It is across the lake from the city of New Orleans and its southshore suburbs. It is part of the New Orleans - Metairie - Kenner metropolitan area.EtymologyMandeville is the name of two villages in Normandy, France. It means "big farm" (from Magna Villa) in medieval Norman French.HistoryThe area had long been agricultural land when the town of Mandeville was laid out in 1834 by developer Bernard Xavier de Marigny de Mandeville, more often known as Bernard de Marigny. In 1840 Mandeville was incorporated as a town. It became a popular summer destination for well-to-do New Orleanians wishing to escape the city's heat.In the mid-19th century, regular daily steamboat traffic between New Orleans and Mandeville began, and by the end of the Victorian era, it had become a popular weekend destination of the New Orleans middle class as well. Bands would play music on the ships going across the lake and at pavilions and dance halls in Mandeville, and the town became one of the first places where the new "jazz" music was heard outside of New Orleans. Bunk Johnson, Buddy Petit, Papa Celestin, George Lewis, Kid Ory, Edmond Hall, Chester Zardis, and many other early jazz artists regularly played in Mandeville.
