Standing tall as Baton Rouge’s oldest structure is the Arsenal at Oaklawn Manor, built 1836-1838. Initially, this impressive brick building served as the state’s primary armory, safeguarding weapons and supplies during pivotal moments like the Civil War. Its journey beyond an armory saw it become a residence, then an educational facility.

Today, it resides in the LSU Hilltop Arboretum, housing a museum dedicated to Louisiana’s military history.

Inside offers a glimpse into the past through exhibits and artifacts, while the building itself stands as a testament to Baton Rouge’s rich history, weaving a tangible connection to the city’s early days.
