Port Sulphur, Census-designated place in Plaquemines Parish, Louisiana, United States.
Port Sulphur is a census-designated place in Plaquemines Parish, Louisiana, on the west bank of the Mississippi River, surrounded by the wetlands and marshes of the river delta. The terrain is flat and largely covered by water, as is typical of this low-lying section of the Louisiana coast.
The Freeport Sulphur Company began mining the region's sulfur deposits in the 1930s and built what was essentially a company town around its operations. The name Port Sulphur itself comes directly from this industrial past.
Port Sulphur has a close connection to fishing and shrimping, trades that have shaped life along this stretch of the Mississippi Delta for generations. Boats at the docks and local seafood stands make this connection easy to notice on a visit.
Louisiana Highway 23 is the main road through Port Sulphur, connecting it northward toward New Orleans and continuing south into the delta. A car is the most practical way to get around, as there is no public transport in this area.
When the sulfur company withdrew, the layout of the community stayed largely the same because it had been built as a planned company town with a grid of streets and services all designed around the industry. Walking through today, the structure of that original plan is still readable in how the streets and blocks are arranged.
