Around 1858, the Vulcan Iron Works opened on the eastern part of the site now known as the Carondelet Coke Plant. This site was bounded by Catalan Street on the north, the Mississippi River on the east, the River Des Peres on the south and railroad tracks on the west. This plant produced iron from ore, and was one of the first such concerns on the south riverfront of St. Louis. The plant was served by the St. Louis, Iron Mountain and Southern Railroad, whose line remains in use today by Union Pacific. North of Vulcan Iron Works, on the site recently home to St. Louis Ship, stood the works of the Carondelet Marine Railway. The marine railway conveyed boats out of the river via rail cars that went under the keels while the boats were in the river and then brought them onto dry land for repairs. The works existed from the 1850s onward. During the Civil War, the Marine Railway became home to a new use: construction of gunboats for the Union war effort. Engineer James Buchanan Eads leased the works, which became known as Eads’ Union Marine Works or the Union Iron-Works. His company became St. Louis Ship-Federal Barge, which closed around 2001.

The 1883 Hopkins fire insurance map shows the Vulcan Iron Works site occupied by the St. Louis Ore and Steel Company, owned by Western Steel Company. The map shows blast furnaces, a converting mill, a rail mill and a bloomery and bar mill on the site. The Western Iron Boat Building Company had a facility just north of there and south of the Carondelet Marine Railway Site. Early on, iron ore from southeast Missouri was a valuable thing, but when better deposits were found around Lake Superior, the Missouri iron industry shrank. Laclede Gas and Light Company purchased the site in 1902 for the purposes of building a coal gasification plant. Coal gasification breaks down coal into various gaseous components, which at that time were needed for the household gas much of the city used for lighting and cooking.

Coal gasification produces many other valuable byproducts, including coke, and utility companies engaging in early gasification efforts began creating co-generation facilities that would produce both gas needed for household use and coke needed for steel production. In 1915, Laclede Gas and Light built new buildings designed by the noted firm Mauran, Russell & Crowell and installed new equipment at their plant on Catalan Street. This expansion created gave the plant coke production abilities on par with major coke ovens in other cities. The operation continued after natural gas became a much cheaper source for household gas than gasification. In 1950, Laclede Gas and Light sold the plant to the Great Lakes Carbon Company, which concentrated on coke production. The company operated the plant for thirty years before selling to local owners organized as the Carondelet Coke Corporation.

In 1987, Carondelet Coke Corporation closed the coke works, which had been mentioned in a US Environmental Protection Agency report that asserted that coke works were the most carcinogenic type of American industrial facility. By 1989, unpaid taxes led to the property’s being acquired by the city of St. Louis’ Land Reutilization Authority (LRA). At forty acres, the plant became the largest property owned by the LRA. LRA solicited sales from time to time, but with contamination levels high, could not find a responsible buyer. The flood of 1993 washed across the grounds, spreading slag and coke piles across the eastern part of the site and knocking down a few structures.

Over the years, the site of robust industry returned to first nature as vegetation and animals took over the site. Youth found the site a good place for exploration and rabble-rousing. Some brave squatters moved in. Yet almost twenty years after the plant closed, in 2006, the city of St. Louis finally found a developer willing to remake the site. The plan calls for demolition of all structures and construction of light industrial buildings.
