Historical Significance:

​

Built between 1850 and 1852 by Luxembourg tobacco merchant Jean Baptiste Lang, this classic Creole cottage reflects the prosperity of antebellum New Orleans and Mandeville's role as a summer retreat. Today, the Jean Baptiste Lang House Museum showcases its original craftsmanship, including faux bois finishes, mortise-and-tenon construction, and other distinctive Creole architectural features. Recent restoration has revealed historic colors and woodwork, offering a glimpse into one of Mandeville's finest 19th-century summer homes.

​

Preservation Effort:

​

Old Mandeville endured the Civil War, Reconstruction, and decades of change, remaining a rare historic enclave until Hurricane Katrina threatened its survival in 2005. The storm damaged many historic homes, leading to the creation of Mandeville's Historic Preservation District. After Katrina, the Jourdan family donated the Lang House to the City, which relocated it to the Kierr Family Garden. The Old Mandeville Historic Association restored the home, preserving an important piece of the town's history.

 

Current State:

​

The Jean Baptiste Lang House Museum serves as a multi-functional community space. It officially opened its doors to the public in December of 2014 at which time the majority of restoration had been completed.  

Since the inception of the Old Mandeville Historic Association in 2011,  significant research on Mandeville’s unique history has been uncovered. If you have an interest in architecture, your home’s chain of title, historic restoration, or Louisiana history,  visit the Jean Baptiste Lang House Museum and take the tour. Our gift shop offers local gifts and educational publications.​
