Middle Bay Light, also known as Middle Bay Lighthouse and Mobile Bay Lighthouse, is an active hexagonal-shaped cottage style screw-pile lighthouse. The structure is located offshore from Mobile, Alabama, in the center of Mobile Bay. [3] [4] [5]
The station was activated in 1885. In 1916 the keeper's wife gave birth to a baby that summer at the station. According to the Alabama Lighthouse Association web site, the keeper brought a dairy cow to the station and corralled it on a section of the lower deck because his wife was unable to nurse the newborn baby. All had to be evacuated when the station survived but was damaged by a hurricane that year. The light was automated in 1935.
The lighthouse was placed on the National Register of Historic Places on December 30, 1974. [2] In 1984 the lighthouse was stabilized by Middle Bay Light Centennial Commission in preparation for the centennial celebration. In 1996 the Coast Guard loaned the original Fresnel lens to the Ft. Morgan Museum for public display. In 2002 restoration efforts were begun to repair the lighthouse.
In 2003, a real-time weather station was added to the lighthouse by the Dauphin Island Sea Lab and the Mobile Bay National Estuary Program. This program is now called ARCOS (Alabama's Realtime Coastal Observing System) and is still active today The weather station, one of seven in Mobile Bay, samples precipitation, total and quantum solar radiation, air temperature, relative humidity, wind speed and direction, barometric pressure, water temperature, salinity, water depth, and dissolved oxygen. These data can be viewed in real time. [6] From late 2011 - mid 2014 currents and waves were also displayed.
Whale oil was the first fuel used and the lighthouse tenders worked in shifts making sure that the lamps did not go out and smoke the lens. In later years kerosene was used and eventually they were converted to electricity. [7]

The Mobile Point Range Lights were a series of lighthouses at the entrance to Mobile Bay, at Mobile Point on the tip of the Fort Morgan peninsula, near Mobile, Alabama, United States. The first lighthouse was built as a landfall light by June 1822 at a cost of $9,995. The lighthouse was a conical brick masonry tower, 40 feet (12 m) tall. It was first lit on 29 September 1822. Fort Morgan was built adjacent to the lighthouse in 1833. The lighthouse was joined by the 200-foot (61 m) Sand Island Light across the mouth of the bay, about 3 miles (4.8 km) away in 1858. This resulted in the Mobile Point Lighthouse being downgraded to a harbor light, at the same time a fourth order Fresnel lens was installed. A period photograph, taken prior to the American Civil War, shows two shorter masonry towers standing on the beach below the main tower, they served as range lights. The lighthouse was subsequently destroyed by cannonball fire in the Battle of Mobile Bay during the Civil War.

Ned Point Light is a historic lighthouse on Ned's Point Road in Mattapoisett, Massachusetts. The lighthouse was built in 1838 at a cost of approximately $5,000, and named after Ned Dexter, a local farmer. Under the supervision of a local builder, Leonard Hammond, the lighthouse was constructed with a birdcage-style lantern similar to Bird Island Light found in Marion, Massachusetts. The stone used for the lighthouse was all locally sourced, with most of it originating from nearby beaches. Inside, there are 32 granite steps that are cantilevered to the outside wall without the use of mortar. The original lantern used 11 whale oil lamps, each with its own parabolic reflector. The lamps and reflectors were replaced by a fifth order Fresnel lens in 1857, along with a change to an octagonal lantern. The Great Blizzard of 1888 significantly damaged the keeper's stone house, resulting in it being demolished and the building of a wooden replacement.
