[1] It formerly served as a treatment facility for leprosy, and was called the National Leprosarium, Gillis W. Long Hansen's Disease Center and Public Health Service Hospital No.

[2][3] Located on the eastern bank of the Mississippi River in Carville, Louisiana, the National Leprosarium was one of two leprosy hospitals in the United States.

But in the early days, there was no effective medical treatment, and patients entered the gates under mandatory quarantine and many never left the hospital again.

[7] Over the next century, the property would develop into a world class hospital, housing hundreds of employees and patients, including married couples and children.

Long was successful in lobbying Congress to keep Carville open for the patients who wanted to remain on site, even though mandatory quarantine ceased to be law some years before.

[11] The National Hansen’s Disease Museum's exhibits include a history of the Carville facility, the United States Public Health Service and Daughters of Charity of St. Vincent de Paul who cared for the residents.

It wasdesigned and built by New Orleans architect Henry Howard (and perhaps his partner Albert Diettel) in 1859 for sugar planter Robert C. Camp.

It is a raised stucco over brick transitional Greek Revival Italianate mansion featuring a central mass with a hexastyle double gallery and flanking two-story wings.

Column capitals are correctly fashioned from double rows of acanthus leaf carvings with volutess or scrolls springing from the centers.
