Gentilly sits on a natural ridge created by Bayou Sauvage, a former flood plain. California bungalow style houses, most of them constructed from 1910-1940, English cottages, and Spanish- and Mediterranean-revival homes constitute this national historic district, the first 20th century New Orleans neighborhood to be listed.
The high ground and natural drainage with easy access to the city made this a prime section for development shortly before World War I. The Pontchartrain Railroad, built in 1830, provided transportation through the Gentilly district. It ran along Elysian Fields to Lake Pontchartrain.
Settlement was originally mostly confined to along the long narrow ridge, plus Milneburg, built on elevated piers on the shore of Lake Pontchartrain. Most of the ground between the ridge and the lake was swampy. The first residential section adjacent to the ridge, Gentilly Terrace, dating to the early 20th century, was built by excavating and piling up the earth in the shallow swamp to create blocks of terraced land where houses could be built. With the development of improved drainage pumps, land reclamation and higher lakefront levees, the land extending from the ridge to the lake was developed by the mid-20th century, and the entire area popularly came to be known as Gentilly.
Today, the ambience and architecture of Gentilly is a refreshing departure from the din of the city. With a diverse mixture of residential properties, commercial developments and schools, Gentilly remains one of the most unique and charming neighborhoods of New Orleans.
