💡 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.
