Madisonville was founded by
Jean Baptiste Baham in 1800, before the United States acquired this area, as the town of "Coquille" or "Cokie" because of the abundance of shells in the area, at the site of the Native American village of "Chiconcte". The town was renamed in honor of US President
James Madison around 1811. Madisonville was a notable port, providing bricks and other products of the towns along the
Tchefuncte River to
New Orleans, in the decades before the
Civil War. After the
Capture of New Orleans by the
Union Army, this area remained under nominal
Confederate control; and the cutoff of trade with New Orleans across enemy lines was devastating to the local economy, which did not recover for decades after the peace. The opening of the
Lake Pontchartrain Causeway and associated highways gradually brought Madisonville into the sphere of
Greater New Orleans, in the second half of the 20th century. Much of the town flooded with the
Lake Pontchartrain storm surge of
Hurricane Katrina, on August 29, 2005. The police/fire station and the town hall were damaged by the flood waters. The town flooded again in 2012 during
Hurricane Isaac. Town buildings were again repaired but the police station was moved to a historic building at the intersection of Covington, St. John and Cedar Streets. The fire station later moved to a new building on Hwy. 22 just west of the town center.
Jahncke shipyard Frederick (Fritz) Jahncke emigrated to New Orleans from
Hamburg, Germany in 1870. After working as a mason, he started a business that built the first sidewalks in New Orleans. Jahncke expanded; using a rented steam-driven hydraulic suction dredge, his firm was the first to extract sand and shell from the Tchefuncte and other rivers to make concrete used in expanding New Orleans. Jahncke purchased a half-interest in the Baham Shipyard, entering into shipbuilding. In 1905 he purchased the remaining interest, acquiring land for yards, as well as warehouses, docks, storage facilities and equipment. He died in 1911 and the company passed to
Ernest Lee, Paul F. and Walter F. Jahncke. In 1917, the company started building five wooden ships for the US Navy for
World War I. Two ships were completed – the
SS Bayou Teche, which was launched in March 1918, and the
SS Balabac on September 29, 1918. The war ended November 11, 1918, and three of the ships were not completed. The
SS Abbeville was completed on January 19, 1919, and the
SS Pontchartrain on April 6, 1919. The last ship was hauled across the river and burned. Part of the hull is still visible at low tide. The Jahncke Shipyard, once a hub of shipbuilding activity during World War I, is no longer operational. While the shipyard itself is now a historical site, its legacy lives on in the maritime industry in the area. Just 2 miles downriver from the original Jahncke Shipyard site is Marina del Ray, which has grown to become the largest marina in the region, serving as a key facility for local boaters and visitors alike. ==Geography==
