Louisiana towns list more on the Register than most of the country (a typical Louisiana town has 3.8 per 10,000 residents, the U.S. 2.4), so Gramercy’s 142 sits above most of its state (92% of Louisiana towns have fewer) while its 40 historic buildings outnumber those of 83% of U.S. towns.

What stands out about Gramercy’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Gramercy was originally an American Indian and French settlement and trading post. In 1739, much of the area which is now known as Gramercy was sold to Joseph Delille Dupart, Commissioner of Indian Nations under
Jean-Baptiste Le Moyne de Bienville. The town was incorporated in November 1947. A historic sugar mill was established in Gramercy in 1895, which became the Colonial Sugar Refinery in 1902. The National Park Service has designated the site as the Colonial Sugar National Historic District.
