Carville is a neighborhood of St. Gabriel, located in Iberville Parish in southern Louisiana, sixteen miles south of Baton Rouge, on the Mississippi River.

Best known as the childhood hometown of famed political consultant James Carville, it is also known for its sixty-five-year history as the only place in America to treat leprosy until outpatient treatment became viable in 1981.

[1][2][3] Nowadays, that legacy is celebrated at the National Hansen’s Disease Museum, which educates visitors about the condition.

The result was a U.S. Public Health Service hospital named "Carville National Leprosarium," and dedicated to treating leprosy.

Named for the late U.S. Representative Gillis William Long, a Democrat from Louisiana's 8th congressional district, it is operated by the Louisiana Army National Guard, and the facility now includes the National Hansen’s Disease Museum.
