The original Cabildo was destroyed in the Great New Orleans Fire. The Cabildo was rebuilt between 1795–99 as the home of the Spanishmunicipal government in New Orleans, in 1821 Spanish coat of arms removed from the façade pediment and replaced with the extant American eagle with cannonballs by the Italian sculptor Pietro Cardelli and the third floor with mansard roof was later added in 1847, in French style. The building took its name from the governing body who met there—the "Illustrious Cabildo," or city council. The Cabildo was the site of the Louisiana Purchase transfer ceremonies late in 1803, and continued to be used by the New Orleans city council until the mid-1850s. The building's main hall, the Sala Capitular, was originally utilized as a courtroom. The Spanish used the courtroom from 1799 to 1803, and from 1803 to 1812 it was used by the Louisiana territorialsuperior court. During the years between 1868 and 1910, the Cabildo was the seat of the Louisiana Supreme Court. The Sala Capitular was the site of several landmark court cases, including Plessy v. Ferguson. In 1895 the building was in a state of decay and proposed for demolition; artist William Woodward led a successful campaign to have the historic building preserved and restored. In 1911, the Cabildo became the home of the Louisiana State Museum. The museum displays exhibits about the history of Louisiana from its settlement up through the Reconstruction Era, and about the heritage of the ethnic groups who have lived in the state. It was declared a National Historic Landmark in 1960. The Cabildo was extensively damaged by a fire on May 11, 1988, which destroyed the cupola and the entire third floor, but it was restored and reopened to the public in 1994. In 2005, the Cabildo survived Hurricane Katrina, the eye of which passed 30 miles east of downtown, with relatively minor damage. Days after the storm struck, the Louisiana State Police used the business offices of the Cabildo to set up what was called Troop N. From the Cabildo, state troopers patrolled the city's streets along with police agencies from New Mexico and New York.
