Plaquemine Lock State Historic Site 57730 Main Street, Plaquemine, LA 70764

Located at 57730 Main Street in Plaquemine, Louisiana, the Plaquemine Lock State Historic Site is a popular tourist attraction with a rich history. This site was once a vital navigational route, connecting the Mississippi River to the heartland of Louisiana through Bayou Plaquemine. Designed by Colonel George W. Goethals, the lock was completed in 1909 and was known for its innovative engineering design and impressive freshwater lift of 51 feet.

Over the years, the lock played a significant role in promoting settlement and economic prosperity in the region. However, increased river traffic after World War II led to the construction of larger locks at Port Allen, resulting in the closure of the Plaquemine Lock in 1961. Despite its closure, the lock's historical significance was recognized in 1972 when it was placed on the National Register of Historic Places.

Visitors to the site can explore the Gary James Hebert Memorial Lockhouse, which now serves as a museum and visitors center. The area also features a stylized adaptation of the Lockmaster's house, providing a glimpse into the past with displays of watercraft used when the lock was operational. With its fascinating history and well-preserved structures, the Plaquemine Lock State Historic Site offers a unique glimpse into Louisiana's rich heritage.
