Pass Manchac Light

Pass Manchac Light was a historic lighthouse in Tangipahoa Parish, Louisiana, which was originally established in 1838, to mark the north side of the entrance to Pass Manchac, the channel between Lake Pontchartrain and Lake Maurepas. The fourth and last tower on this particular site was constructed in 1857 and was in service for 130 years. The first three had been built in 1838, 1842, and 1846, in each case requiring replacement due to poor construction and/or encroaching lake waters.[2]

History

The 1857 lighthouse, a brick cylinder with attached house, was damaged in the Civil War and during tropical storms in 1888, 1890, 1915, 1926, and 1931. The station was automated in 1941, and the keeper's house was removed in 1952, by which time the light was on an island instead of a peninsula.[2]

Pass Manchac Light was added to the National Register of Historic Places in 1986. The light was functionally replaced in 1987 by the U.S. Coast Guard, which established a skeleton tower on the south side of the pass entrance.[1]

On August 28, 2012, Louisiana was struck by Hurricane Isaac, destroying the lighthouse. It was removed from the National Register in January 2019.

However, since February 2008 its lantern room – which was removed from the tower in 2002 for restoration – has been located at the Lake Pontchartrain Basin Maritime Museum, in Madisonville, Louisiana.[7]

gollark: If you *do* go around using a definition which admits stars and everything else, it's basically meaningless, but ends up bringing all the weird things English ties to "life" and "organisms" along with it anywya.
gollark: Which are mostly for some specific technical context and make sense there. Because it's a hard to define word.
gollark: The broader issue is that when people say stuff like that they generally mean to sneak in a bunch of connotations which are dragged along with "organism" or "life".
gollark: You could *maybe* stretch that to extend to *all* humans, but *also* probably-not-organism things like stars, which also reproduce (ish), process things into usable energy (ish), sort of respond to stimuli for very broad definitions of stimuli, maintain a balance between radiation pressure and gravity, and grow (ish).
gollark: Individual humans are "organisms" by any sensible definition, inasmuch as they... reproduce, think, maintain homeostasis, grow, respond to stimuli, process inputs into usable energy and whatever.
