History & History Related Items

Incorporated as a town in 1840, Mandeville was originally used as a retreat for the wealthy families of New Orleans, who came to escape the heat of the city and threat of disease, mainly Malaria. Before the bridge was built, people came over Lake Pontchartrain with the steamer ferry service. Once the first span of the 24 miles Causeway bridge was built in 1956, and a second span in 1969, growth rapidly became the rule. Many families moved the to area while maintaining their business and work back in New Orleans. Mandeville then became accessible to the less wealthy people and subdivisions began to pop up over the area.
On June 18, 1985, then governor, Edwin W. Edwards, proclaimed the "City of Mandeville" from the town of Mandeville. The population of the Mandeville had grown to over 5,000 persons.

The Parish was named for Delaware Indian Chief, Tamenand. The area remained largely unsettled until 1785 when settlers from Georgia and the Carolinas came into the territory. Settlements were formed along the local rivers and bayous.
