Longue Vue House and Gardens is an internationally recognized historic house museum and gardens that has provided unique and vital resources to the greater New Orleans community for the past 25 years. Longue Vue's magnificent grounds are a product of the Country Place Era that flourished from the 1890s until the Great Depression. Longue Vue was designated as a National Historic Landmark in 2005, accredited by the American Association of Museums in 1986 and listed on the National Register of Historic Places in 1991. The Longue Vue property is collaborative tour-de-force, combining the landscape and interiors of landscape architect Ellen Biddle Shipman, the architectural genius of William and Geoffrey Platt, and the horticultural knowledge of Caroline Dormon. The house is an extraordinary example of the Classical Revival style and one of the last great houses of the American Architectural Renaissance. Longue Vue is considered to be the master residential work of William and Geoffrey Platt and the masterwork of Ellen Biddle Shipman—once called “the dean of American women in landscape architecture.”
