Pass Manchac Lighthouse

A 175-year-old lighthouse that stood at Pass Manchac was knocked over by Hurricane Isaac's strong surge.

WWL-TV reports that the landmark in Tangipahoa Parish now lies crumbled in the water. The Pass Manchac Lighthouse was erected at a pass connecting lakes Maurepas and Pontchartrain.

Al Dranguet, a professor of history at Southeastern Louisiana University, said the lighthouse was a beacon of safety for many generations.
