Cape Lookout Light
Cape Lookout National Seashore, North Carolina.
The light is the second to be built on the cape. The first in 1812 and the present in 1859. The diamond pattern is a distinctive aid during daylight and a "fresnel" lens shines at night. The light warns mariners of the treacherous lookout shoals [called Promontorium Tremendum or "Horrible Headland" on old maps] that extend for 10 miles into the blue Atlantic.
Hundreds of ships have been lost here and in WWII the inlet provided one of the few safe havens from German U-Boats patrolling the shores.
