Jackson Square, located in the heart of New Orleans was designed by architect Louis H. Pilié, and modeled after the famous Place des Vosges in Paris, France.

The square, known during the colonial era as the Place d' Armes, by the French and the Plaza de Armas by the Spanish, served as the central meeting place for both the city's government and citizens.

The north side of the square is home to St. Louis Cathedral the seat of the Arch-diocese of New Orleans and flanked on either side by the Cabildo which served as headquarters of the New Orleans government until the 1850s and the Presbytère, originally constructed as a home for Capuchin Monks.

In 1803, the American Flag was raised for the first time over the newly acquired Louisiana Purchase in the center of Jackson Square.

Following the Battle of New Orleans, in 1814, the square was renamed in honor of General Andrew Jackson. In 1858 a large statue was designed and erected by American Sculptor Clark Mills at the heart of the square.

During the 18th and 19th centuries, citizens utilized the square for public executions and other demonstrations, including militia drilling and mustering.

When first constructed the square maintained access across Decatur street to the riverfront. However, the construction of the levee system during the 19th century along with the revitalization of the river walk area in the 1970s now hides the water view from the square.

Throughout the history of New Orleans, Jackson Square has served as the heart of the city and continues to do so today. The Square was officially designated a National Historic Landmark in 1960.
