Of the lighthouses covered in this list, the Statue of Liberty is the most unusual - both in form and purpose. All along, it was more statue and monument and not really a lighthouse, even though there was a series of effort made to improve its lighthouse effectiveness.
The Statue of Liberty was dedicated to the United States by the French government on 28 Oct 1886. Despite efforts by the United States Lighthouse Board to enhance the effectiveness of its torch, the Statue of Liberty remained virtually invisible at night. In 1901, President Theodore Roosevelt ordered the transfer of the statue to the War Department, due to its effectiveness as a lighthouse. Today, it is designated as a national monument under the care of the National Park Service.
