Orfordness (or Orford Ness) Lighthouse, Suffolk, England
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.
