Capitol Park Museum in Baton Rouge is a branch of the Louisiana State Museum devoted to Louisiana’s history and culture. Its permanent galleries unite political, social, and cultural stories of the state in two broad exhibitions. Designed by the New Orleans studio Eskew Dumez Ripple, with exhibits created by Christopher Chadbourne & Associates, the museum brings together objects that reflect the breadth of Louisiana’s past. Notable holdings include the Bayou St. John submarine and Louis Armstrong’s childhood bugle, linking the collection to both unusual technological artifacts and the state’s musical legacy. It stands as one of Baton Rouge’s key museum sites.
