Lighthouse · Ottawa County, Ohio

Marblehead Light is a lighthouse in Ottawa County, Ohio. Ohio has 21 lighthouses on record at Wayfarrow, 6 of them in Ottawa County.

It was built in 1821, in the first half of the 19th century, making it the oldest of the 19 in Ohio with a recorded construction date; the tower stands about 65 feet tall (4th tallest of 12 measured in Ohio); its light sits 67 feet above the water; the light characteristic is recorded as Fl G 6s (a green flash every 6 seconds), with a range of about 11 nautical miles; the structure is built of limestone.

Status check, 2026-11: Sources date the limestone tower to 1821, not 1822 as the record says; it was raised 15 ft in 1897 and is the oldest light in continuous operation on the US side of the Great Lakes (Wikipedia lists 50 ft, which looks like the height before 1897). Marblehead Light is listed on the National Register of Historic Places. It stands at 41.5364° N, 82.7117° W.
