How one woman’s architectural tantrum transformed New Orleans’ “most villainous” square

Baroness de Pontalba’s $300,000 Jackson Square Makeover

In 1819, New Orleans’ main plaza was an eyesore of “mean stores” with “villainous roofs. ” Then came Baroness Micaela de Pontalba, fresh from Paris with big plans.

She fired two architects who got in her way and took charge herself, often climbing ladders in men’s work clothes to check the job.

From 1849 to 1851, she spent over $300,000 to build two matching red-brick buildings with cast iron galleries—a first for the city.

Her project turned a shabby square into the elegant Jackson Square we know today, with each building housing sixteen townhouses above street-level shops.

The Pontalba Buildings still stand as monuments to one woman’s vision that changed New Orleans forever.

A Two-Year-Old Girl Inherited the Heart of New Orleans in 1798

When Don Andrés Almonester died in 1798, he left all his New Orleans properties to his daughter Micaela, who was just two years old. She got rundown buildings around the Plaza de Armas, now called Jackson Square.

Her father had already paid to rebuild St. Louis Cathedral, the Cabildo, and the Presbytère after a big fire in 1788.

By 1819, architect Benjamin Latrobe called the remaining buildings “very mean stores covered with most villainous roofs.

Marriage at 15 Began Decades of European Drama

Micaela married her French cousin Célestin de Pontalba at age 15 in 1811, moving her to France. Her father-in-law, the Baron de Pontalba, tried many times to take her New Orleans inheritance through threats.

Things turned violent in 1834 when the Baron shot Micaela four times up close after she refused to sign over her properties. She lived but had lasting scars.

The Baron killed himself that night. She fought in court for years to keep her American properties.

New Orleans Had Fallen into Decay When She Returned

The Baroness came back to New Orleans in 1848 with her sons Alfred and Gaston after the French Revolution started. She found Plaza de Armas turned into a slum with a muddy parade ground and falling-apart buildings.

Her properties were worth $520,000 but made little money because tenants didn’t pay rent. New Orleans had grown into the fifth-largest U.S. city, but the French Quarter was crumbling fast.

She needed to take bold action.

The First Architect Got Fired Before Construction Started

In 1849, the Baroness hired famous architect James Gallier Sr. to draw plans for her big project.

She wanted two matching buildings to replace the old structures on both sides of the square. They fought quickly, with building contracts showing Gallier’s name crossed out with “Nul” next to it.

Some clues suggest the Baroness brought her own plans from France, possibly made by Louis Visconti, who designed her Paris home.

She Claimed She Was “A Good Architect Herself”

After Gallier left, architect Henry Howard stepped in but didn’t last long either. Howard later said the Baroness bragged “she was a good architect herself and said she built a great deal in France.”

He asked for $500 for his work but got just $120 for watercolor drawings of the buildings. Howard quit after fighting with the Baroness over who controlled the design.

Builder Samuel Stewart then handled construction without an architect’s help.

The Baroness Climbed Construction Ladders in Men’s Clothes

Building started in spring 1849 on both the Upper and Lower Pontalba Buildings at the same time. The Baroness watched every detail, reportedly wearing men’s work clothes and climbing up construction ladders herself.

Each building had sixteen fancy townhouses with shops on the ground floor.

Materials came from all over, pressed red brick from Baltimore, New England granite, and English slate roof tiles. Without an architect in charge, the project ran late and cost more than planned.

Cast Iron Balconies Became a New Orleans Fashion Trend

The Pontalba Buildings showed off the first known cast iron galleries in New Orleans. The ironwork included an AP monogram (for Almonester/Pontalba) designed by her son Gaston.

These cast iron balconies caught on fast, shaping French Quarter style for generations. The design mixed ideas from the Parisian Place des Vosges with local Creole cottage layouts.

This new look now defines what most people think of as New Orleans style.

The Builder Sued Her After the $300,000 Project Finished

Workers finished the Upper Pontalba Building in 1850 and the Lower Pontalba in 1851. The total cost topped $300,000, a huge sum back then.

Builder Samuel Stewart took the Baroness to court to get paid after she argued about his final bills. The court case, Stewart v. Pontalba, gives us detailed records of the construction. Local newspapers praised the buildings for their beauty and value to the city.

Her Project Sparked a Complete Makeover of the Square

The Baroness’s big buildings pushed others to fix up the rest of Jackson Square. St. Louis Cathedral and the Cabildo got updates to match the new buildings. The city put up iron fencing around the square and laid flagstone sidewalks in 1851.

The Andrew Jackson Monument Association raised money for the famous horse statue. That same year, officials changed the name from Place d’Armes to Jackson Square.

Famous Opera Singer Jenny Lind Became One of Her Tenants

The buildings quickly drew high-status tenants, including famous singer Jenny Lind. The Baroness lived in an Upper Pontalba townhouse herself, keeping watch over her creation.

The ground floor spaces held dry goods stores, lawyers’ offices, a bank, and clothing shops. The buildings became the center of New Orleans high society and a popular gathering place.

She Left Her Buildings Behind Just as They Made New Orleans Famous

In March 1851, the Baroness left New Orleans for good, returning to Paris to reunite with her estranged husband. Her buildings established a lasting template for Jackson Square as a mixed civic and commercial space.

The cast iron architectural style she introduced spread throughout the French Quarter and beyond.

Today, the Upper Pontalba belongs to the City of New Orleans, while the Lower Pontalba is owned by the State of Louisiana.

Her project turned a randomly developed area into a cohesive, sophisticated urban center that remains an iconic symbol of New Orleans.

Visiting Pontalba Buildings, Louisiana

You can explore Baroness de Pontalba’s revolutionary urban transformation at the 1850 House Museum in the Lower Pontalba Building at 523 St. Ann Street.

Admission costs $8 for adults and $6 for seniors, students, and active military.

The museum is open Tuesday through Sunday and showcases period furniture, Old Paris porcelain, and New Orleans silver from the mid-1800s.

Her Parisian-influenced architecture started the citywide iron gallery trend that defines New Orleans today.
