Ranked among the most historically significant buildings in America, the Cabildo is an essential stop for anyone interested in New Orleans’ rich history. In addition to being the seat of city government until 1853, it was also served as the Louisiana State Supreme Court during the landmark Plessy v. Ferguson decision 1892, which upheld the constitutionality of racial segregation.
Today, the inside of the Cabildo is open to the public as part of the Louisiana State Museum. Collection highlights include a copy of Napoleon's death mask and an elaborate Mardi Gras costume. Many French Quarter walking tours stop outside the building for a quick discussion of its historical importance.
