Orfordness (or Orford Ness) Lighthouse, Suffolk, England
Moving Lighthouses to Save Them: Cape Hatteras, North Carolina

Many small lighthouses have been moved to save them from beach erosion. Some are picked up by helicopter and set down at a safer distance from the sea. But in 1999, the world watched as North Carolina's 210-foot (64-meter) high Cape Hatteras Lighthouse was moved 2,900 feet (884 meters) from where it was built in 1870. After study and debate among scientists, engineers, preservationists, the U.S. National Park Service and the public, the lighthouse was saved by moving it. As people watched via webcam, jacks successfully lifted the lighthouse off its base, put it on rollers and moved it along a prepared route.

The only way to save this endangered lighthouse is to move it. This 98-foot (30-meter) high round brick lighthouse has stood on a small island on Suffolk's North Sea since 1792. In late 2010, its light is still in use. But the sea has been eroding the place where the lighthouse stands, and if it's not moved soon, it will fall.

Britain's National Trust operates the remote area as a nature reserve and historic site. Trinity House, which has been responsible for shipping and seafarers' safety since the days of Henry VIII, has announced that the lighthouse will crumble within a few years and will be abandoned. There have been protests against this decision, but no one seems to have the money to move the lighthouse.

The lighthouse has withstood raids by pirates, storms and enemy attacks, but if something isn't done soon, it will fall victim to the sea.
