Annual cultural events
Plaquemine is noted for a number of antebellum structures that survive within the city limits and along Bayou Road. One of the most noteworthy homes is St. Basil's, a riverfront mansion built by socialite physician Dr. John Scratchley in the 1850s. Now a private residence, the home retains the name St. Basil's from when it was a fashionable convent school. 
The Iberville Museum was built in 1949 as the Iberville Parish Courthouse. The building served as Plaquemine's first city hall, and was the city seat of government until 1985. It now serves as a parish museum, and the building is on the National Register of Historic Places.
The Plaquemine Lock, constructed from 1895 to 1909, was an important link between the Mississippi River and the Intracoastal Canal, of which Bayou Plaquemine served as its northern terminus. Its design served as the prototype for the Panama Canal locks; the Plaquemine Lock was shut down in 1961. In 1974, the U.S. Army Corps of Engineers supervised the construction of the levee that runs across the mouth of Bayou Plaquemine at the Mississippi River. The Plaquemine Lock was placed on the National Register of Historic Places in 1972. The area now operates as a state park.
