Franklin Island Light
Lighthouse · Knox County, Maine

Franklin Island Light is a lighthouse in Knox County, Maine. Maine has 70 lighthouses on record at Wayfarrow, 15 of them in Knox County.
It was built in 1855, in the Civil War era, making it the 14th oldest of the 61 in Maine with a recorded construction date; the tower stands about 45 feet tall (17th tallest of 53 measured in Maine); its light sits 56 feet above the water; the light characteristic is recorded as Fl W 6s (a white flash every 6 seconds), with a range of about 8 nautical miles.
Status check, 2026-11: The station dates to 1805 (first tower finished 1807), but today's 45 ft brick tower was built in 1855, so the record's 1805 is the station's founding year, not the tower's. It is not reachable by road: the nearest road is about 4 miles away, so it is seen from shore or reached by water. It stands at 43.8921° N, 69.3746° W.
