The Craighill Channel Lower Range Front Light Station is located about two miles off the shore of North Point State Park. It doesn't have an address. But it goes by the longitude of 39.188614 and latitude of -76.394399.
The light station dates back to 1873, when it was first lit, according to the government site hosting the auction.
The tower features a 1.5-story keeper quarters with a perimeter deck, the listing says. The lantern room sits about 25 feet above the water.
Don't get any ideas about creating a wind farm or mid-bay resort or anything — that land under the light house? It'll stay in government ownership. And, according to the listing, "the buyer will be obligated to acquire and maintain a right of occupancy accordingly."
