The large brick Plaquemines Parish Government building located on Louisiana Highway 23 (LA 23) in town next to the former Freeport property was originally the Freeport Sulphur Company administration building. The Port Sulphur school and other buildings located around the Civic Drive area were originally located on company property and are oriented towards the former Freeport Property. Much of the original town buildings were sold or removed, and much of the original town site sits mostly vacant empty land, with a large stand of oak trees on the former Freeport Property next to the Plaquemines Government building. An historical marker about Port Sulphur is located in front of the Government Building. The golf course land located on LA 23, just south of the former Freeport property, was originally a neighborhood of the company townsite. The land was later donated to the Plaquemines Parish Government.
