Owls Head Light is an active lighthouse at the entrance to Rockland Harbor in Owls Head, Maine, on the western side of Penobscot Bay. Established in 1825, it began as a round rubblestone tower and was rebuilt in 1852 as the present cylindrical brick structure on a granite foundation atop a cliff. Though only 30 feet tall, its site gives it a focal height of about 100 feet above mean sea level. The station preserves key historic features, including an 1854 keeper’s house and an 1856 fourth-order Fresnel lens, one of the last six still operating in Maine. Restored in 2010, it remains a working aid to navigation and a prominent coastal landmark.
