Here are America's 11 endangered places

The National Trust for Historic Preservation has been keeping an eye on America's historic places for some time, and since 1988 they've been compiling annual lists of those that are in danger of vanishing.

2015's collection of endangered places includes some of the country's most iconic natural features, buildings, and communities.

Among them is the Grand Canyon, an area celebrated for both its natural beauty and significance in many Native American cultures.

Miami's Little Havana, a neighborhood that has become symbolic of the melding of cultures in America, is another site where longevity has become a concern.

New York City's South Street Seaport, which boasts the nation's largest concentration of restored 19th century commercial architecture, is noted by the trust as well.

Others included on the list of the 11 most at risk sites are Birmingham's A.G. Gaston Motel, the Chautauqua Amphitheater, The Fort Worth Stock Yards, and the old US Mint, located in San Francisco.

The remaining sites noted are Arizona's Oak Flats, West Hollywood's disco-era hotspot The Factory, Georgia's East Point Historic Civic Block, and New Orleans' Carrollton Courthouse.

Since the list was first introduced, it has proven to be a valuable catalyst, resulting in many of the places featured on it being saved.
