This screwpile lighthouse was commissioned in 1883 and had been located at the Northern mouth of the Patuxent River. Not very far from shore to begin with, 80 years of silting made it an easy target to vandals once it was automated in 1962. It was moved a couple miles west to its current location at the Calvert Marine Museum in Solomons, MD in 1975 and restored. There is currently a lighted buoy where it once stood and you can still see the stubs of the old structure's solid iron pilings.
