From the Associated Press:

Missing Cape Cod lighthouse located in California
WELLFLEET, Mass. - Local historians for decades thought the 30-foot tall lighthouse that once overlooked Wellfleet Harbor had been taken down and destroyed in 1925.

Turns out, it had just been moved to the California coast.

The fate of the cast-iron tower was uncovered last year by lighthouse researchers and reported by Colleen MacNeney in this month's edition of Lighthouse Digest.

Wellfleet historian Helen Purcell says the discovery of the lighthouse at Point Montara at the southern end of San Francisco Bay was a genuine shock.
