Old Field Point Light stands at the northern tip of Old Field on Long Island’s North Shore, where it marks a prominent reach of shoreline between Port Jefferson Harbor and Stony Brook Harbor. Begun in 1823 and completed in 1824, it first used whale-oil lamps with a glass reflector, then was replaced in 1868 by a new lighthouse with kerosene lamps and modernized again in 1933 with an automatic revolving light. Though staffed, its caretaker lived in the village hall. Control passed from the federal government to Old Field in 1935, returned briefly to the U.S. Coast Guard during World War II, and later went back to the community.
