President Barack Obama, left, walks around Gay Head Lighthouse while on vacation on Martha's Vineyard in Aquinnah, Mass., Aug. 27, 2009.
The lighthouse is on The National Trust for Historic Preservation 2013 list of 11 Most Endangered Historic Places.
It was the first lighthouse built on Martha's Vineyard in Massachusetts and now is in danger of toppling over the edge of the Gay Head Cliffs. Preservationists say it's threatened by a century of erosion at the oceanfront site and the impacts of climate change.

Delta Airlines terminal 3 - JFK airport, New York
The unique flying-saucer-shaped Worldport Terminal built by Pan Am in 1960 at New York's Kennedy Airport was a symbol of the jet age.
It's where The Beatles first arrived in the U.S., along with millions of other travelers. But it has become rundown and outdated, and asbestos abatement made renovations costly.
Delta Air Lines recently abandoned the terminal for a new building and demolition crews have already begun work on the futuristic structure from the past.
