The Story
Laid out in 1721 by engineer Adrien de Pauger as the French colonial Place d'Armes, this square became the Spanish Plaza de Armas and, in 1803, the stage for the flag ceremonies transferring Louisiana from Spain to France and then to the United States. After the Pontalba buildings rose in 1851, the Baroness Pontalba had it redesigned and renamed for Andrew Jackson, whose equestrian statue was unveiled in 1856.
Why it matters
Here the Louisiana Purchase was formally enacted — the transfer that doubled the young United States and opened the path of westward expansion.
The story behind this marker
AI contextThe era
This open square is one of the oldest deliberately planned spaces in the country, laid out in 1721 when New Orleans itself was only a few years old. In that era it was the Place d'Armes — a military parade ground and civic heart at the center of a French colonial town facing the Mississippi. Colonial towns were planned around such a square, a place for drills, proclamations, markets, and gatherings, with church and government buildings rising around its edges.
The surveyor's grid that gave the square its shape came from the ambitions of a young French empire in North America. France, Spain, and Britain were all maneuvering for control of the continent's interior, and a town at the mouth of the great river was a strategic prize. Whoever held New Orleans held the doorway to a vast watershed reaching deep into the heart of the continent.
That is why the square changed flags. For roughly the second half of the eighteenth century it was Spanish — the Plaza de Armas — as Louisiana passed under Spanish control before returning, briefly, to France. Standing in this one spot, a resident of the eighteenth and early nineteenth centuries could have lived under three different sovereigns without ever leaving home.
People & events
The square's founding is tied to Adrien de Pauger, the engineer who laid out its lines in the spring of 1721, following the master city plan of the colony's chief engineer. Their grid still governs the streets of the French Quarter today — one of the reasons the neighborhood feels so orderly amid its old-world charm.
But the square's most consequential day came in the winter of 1803, when it hosted the flag ceremonies marking the transfer of Louisiana — first from Spain to France, and then, weeks later, from France to the United States. Crowds would have packed the square to watch one banner lowered and another raised, a quiet piece of theater that changed the map of a continent.
Decades later the square was transformed again, this time by the Baroness Pontalba, who built the grand row-buildings that frame two of its sides and, through her efforts, had the square itself redesigned. It was renamed for Andrew Jackson, and in 1856 his equestrian statue was unveiled at its center — a dramatic bronze of the general on a rearing horse. The graceful cast-iron fence that rings the garden dates from this same mid-century remaking, the work of a local city surveyor and a New Orleans foundry.
Its place in the American story
It is hard to overstate what happened here in December 1803. The Louisiana Purchase roughly doubled the size of the United States overnight, and the ceremonies that formally enacted the handover took place on this ground. The transfer opened the door to a generation of westward expansion, settling the question of who controlled the Mississippi and the port at its mouth — a matter on which the young nation's economic future depended.
The square is therefore one of those rare American places where a single spot of earth witnessed a genuine turning point in the country's history. The families who farmed the interior, the rivermen who floated their goods downstream, the settlers who pushed west in the decades that followed — all of them were affected by what the flags on this square announced.
Its later renaming for Andrew Jackson layered on another chapter of the national memory, honoring the general whose fame was bound up with the defense of the very city that surrounds the square. In one plaza, then, you can trace the arc from colonial outpost to American gateway — a compressed lesson in how the nation grew.
If you visit
Come to the square and let yourself feel how deliberately it was made. The symmetry is no accident: the matching row-buildings on two sides, the garden paths, the fence, and the church rising at the head of the space were all composed to work together, and the effect is genuinely grand.
Look up at the rearing bronze horse at the center and walk a slow circle around it — the statue is meant to be seen from every side. Then find the cast-iron fence and run your eye along it, remembering that it has enclosed this garden since the middle of the nineteenth century. Street musicians, artists, and fortune-tellers often gather along the edges, giving the square a living, festive energy that has probably not changed much in spirit over the centuries.
Stand for a moment facing the river side and picture the flag ceremonies of 1803 unfolding right where you are. This is a place to arrive on foot and linger — the natural anchor of any walk through the old city, and a spot where you can stand quite literally at the center of a moment when the country doubled in size.

Bienville monument
New Orleans, LA
Jean-Baptiste Le Moyne, Sieur de Bienville, the French-Canadian colonizer who founded New Orleans in 1718, spent decades governing France's struggling Louisiana colony along the lower Mississippi. Erected in 1955 for the Louisiana Purchase Sesquicentennial, this statue offers the "homage of Louisiana, Canada, and France" to the man who chose the crescent bend in the river where the city still stands.
Town of Carrollton
New Orleans, LA
Surveyor Charles Zimpel laid out Carrollton in 1833 on the former Macarty Plantation, land that had once been the uppermost portion of Bienville's 1719 French grant. The town served as the seat of Jefferson Parish from 1852 to 1874, when it was annexed by a growing New Orleans. Its 1854 courthouse was designed by the noted architect Henry Howard.
Republic of West Florida
St. Tammany Parish, LA
St. Tammany Parish lay within the Spanish-governed West Florida parishes and was not part of the 1803 Louisiana Purchase. In September 1810 residents revolted against Spanish rule and declared the Republic of West Florida, raising their own flag and electing a president. The republic lasted just 74 days before the United States annexed the territory by force in December 1810.

Covington, LA
John Wharton Collins founded the town of Wharton here in March 1813, naming it for his grandfather. Three years later the Louisiana legislature renamed it Covington in honor of General Leonard Covington, a hero of the War of 1812.
