Louisiana State Museum

From the Wikipedia page

The Louisiana State Museum (LSM), founded in New Orleans in 1906, is a statewide system of National Historic Landmarks and modern structures across Louisiana, housing thousands of artifacts and works of art reflecting Louisiana's legacy of historic events and cultural diversity.

The Louisiana State Museum system has its beginnings in the Louisiana Purchase Exposition in 1904 at St. Louis, Missouri. A large number of pertinent artifacts were gathered to be displayed at Louisiana's exhibition at this fair. After the Exposition, it was decided that this collection should be stored, expanded, and displayed. The Louisiana State Museum was established in 1906 to fulfill this role. The Presbytere and the Cabildo buildings, located on either side of the St. Louis Cathedral on Jackson Square, were some of the first properties that the Louisiana State Museum was lodged in. The Louisiana State Museum now has thirteen properties around the state: historic structures, museums open to the public, and modern purpose-built buildings.
