Stonington Harbor Light

Stonington Harbor Light is a lighthouse in Southeastern Connecticut County, Connecticut. Connecticut has 34 lighthouses on record at Wayfarrow, 7 of them in Southeastern Connecticut County.

It was built in 1840, in the first half of the 19th century, making it the 7th oldest of the 28 in Connecticut with a recorded construction date; the tower stands about 35 feet tall (14th tallest of 21 measured in Connecticut); its light sits 62 feet above the water; the light characteristic is recorded as Fl G 5s (a green flash every 5 seconds), with a range of about 13 nautical miles; it was deactivated in 1889; the structure is built of granite.

Status check, 2026-11: The station dates to 1823, but that tower was taken down because of erosion. Its stones were reused for the present 1840 granite lighthouse, which was decommissioned in 1889 and now houses the Old Lighthouse Museum. Stonington Harbor Light is listed on the National Register of Historic Places. It stands at 41.3286° N, 71.9056° W.
