The Cape Elizabeth Light Station had two towers when it was completed in 1828, one with a fixed beam and the other flashing, to aid seamen in determining their positions. The western tower was decommissioned in 1924 after officials determined that it was no longer needed. It is now privately held.
The eastern lighthouse (pictured in this post) is still operational and has been automated. The American Lighthouse Foundation looks after it. The eastern tower, as well as its gardens, are closed to the public. To view the eastern lighthouse, you can park at the The Lobster Shack at Two Lights and walk along Dyer Cove and Dyer Point. The western lighthouse is in a private neighborhood and should not be attempted to view.
You can also check out and park at the Two Lights State Park. It is a public recreation area occupying 41 acres of headland on Cape Elizabeth, Maine, that offers views of Casco Bay and the Atlantic Ocean.
