Lighthouses
A lighthouse is a structure used to house a light source that acts as an aid to navigation for those at sea. It can also use a sound source for warning. They are also used to warn of dangerous coastlines, reefs, and other hazards, while indicating safe entries to harbors. Most remaining lighthouses are automatic rather than being manned. Questions should relate directly to all aspects regarding lighthouses, including their use and history.

Why was North Carolina's Cape Hatteras lighthouse moved?
By 1935, erosion had so threatened the Cape Hatteras lighthouse tower that the water was actually reaching its base. After attempts to hold back the erosion process through dikes and breakwaters proved futile, the tower was abandoned and a functional light placed on a steel tower further inland from the shore. Starting in 1936 hundreds of miles of sand fences were erected and beach grasses planted by the Civilian Conservation Corps (CCCs) program created by President Franklin Roosevelt. The methods proved effective and after several years the shoreline retreated, the program considered a success, and the lighthouse declared safe for use and recommissioned on 23 January 1950. However, continuing erosion of the shoreline over the next five decades necessitated the relocation of the entire tower in 1999. The granite underlying the foundation of the lighthouse was mined out and replaced with steel supports. Using hydraulic jacks, these steel supports then moved the entire tower along a system of track beams. The actual removal operation began on 17 June 1999 and was completed on 9 July 1999. On this date, the tower was then lowered onto a new concrete pad 2900 feet (883m) away, and its temporary steel foundation replaced with brick.

Where did lighthouse keeper stay?
That depends on the location of the lighthouse. If it stood on the coast, there usually was a house nearby for the keeper to stay in. If the lighthouse was on a relatively large island, the house might also be on the island.
On smaller islands, but near the shore, the lighthouse keeper might live closeby on the shore, and take a boat to the lighthouse to service it.
Modern lighthouses also are often unmanned or remotely operated.
ADDED: The more remote lighthouses, or those on very small islands with no extra area for a separate house, had living-accommodation on the ground-floor of the tower itself. It would be no good having the keeper live on shore if he had to attend to an offshore lamp every day, because there would be many times when rough seas would prevent access.
In some cases a "light-ship" was used, usually above shoals on which it was impossible to build a masonry tower. This was a vessel about the size of a deep-sea trawler, fitted with accommodation for the crew, and moored on station. They have been replaced by light-buoys.
What year was the first fire island lighthouse built?
According to the Fire Island Lighthouse Preservation Society's web site: The first lighthouse built on Fire Island was completed in 1826. It was a 74-foot high, cream colored, octagonal pyramid made of Connecticut River blue split stone. The tower was built at the end of the island, adjacent to the inlet. This tower was not effective due to its lack of height. It was taken down and the stone was reused to build the terrace for the present lighthouse. Today a circular ring of bricks and stone are all that remain of the original lighthouse.
