Whitehead Light
The light station on Whitehead Island was authorized in 1804 by President Thomas Jefferson, and went into service in 1807; it is the third-oldest active light station in the state of Maine. The present tower was built in 1852, its design attributed to Alexander Parris, on the basis of its similarity to the Monhegan Island Light, which is known to be Parris' work. The keeper's house is a replacement, built in 1891, the same year the oilhouse was built. The fog signal was added in 1869-70, a consequence of the area's frequent foggy conditions. The complex originally included covered ways between the major buildings, but these have been removed. The station was automated in 1982, at which time the keeper's house was boarded up.
