Pigeon Point lighthouse in Pescadero, California was built in 1871 and houses a Fresnel lens powered by 5 kerosene lamps that are lit once a year, which you might remember from this amazing photo taken last year. The Coast Guard still operates an automated electric light in the tower, but the lighthouse structure is crumbling, a victim of its harsh environment and time. An estimated $5 million to $7 million is needed to fully repair and restore the stone and brick structure. The California State Parks Foundation has raised $400,000 so far, and $54,000 from the National Trust for Historic Preservation and American Express has already provided new windows.
