Mount Desert Light
lighthouse in Maine, United States

Mount Desert Light is a lighthouse on Mount Desert Rock, a small island about 18 nautical miles (33 km; 21 mi) south of Mount Desert Island, in the U.S. state of Maine. While the first light station was established in 1830, the current lighthouse was built in 1847. It was listed on the National Register of Historic Places as Mount Desert Light Station in 1988. It is currently owned and operated by the College of the Atlantic, located in Bar Harbor, Maine.
History
The conical granite structure was one in a series of lighthouses in Maine designed by architect Alexander Parris. A bell tower and fog bell were added in 1858, as well as a new lantern with a 3rd order Fresnel lens. The bell was replaced by a steam-powered whistle in 1889. The present keeper's house was built in 1892. The station was electrified in 1931 and automated in 1977; around that time, the lantern was removed and the lens was replaced aero-beacon. In 1985, a replica of the lantern was installed, and circa (c.) 1995, the aero-beacon was replaced with a VRB-25 lighthouse system.
