'Cape Flattery Lighthouse' was built in 1854. Its first light was displayed from a
first-order lens in 1857 and was Washington Territory's third lighthouse. The house with a 65 foot tower from the center still stands. A fog signal building with a 12-inch steam whistle was built on the island in 1872. The original first-order lens was replaced by a forth-order lens in 1932, then with a modern optic lens in 1977. Although closed to the public, it can be viewed from Cape Flattery via a short 30 minute walk.
