Most of us are aware that animals can be endangered along with our planet's resources, but how often do we think about the buildings and places around us?
Every year, the National Trust for Historic Preservation releases a list of the most endangered historic places in the country. In an effort to raise awareness about the threats these spots face, the list is composed of places with important architectural, cultural or natural significance that are headed toward demolition or suffer from devastating naturally occurring damage.
Since 1988, more than 250 sites have been included on the nonprofit organization's annual lists. Fortunately, dozens of sites have been saved with only a handful lost forever.
Below, this year's 11 most endangered sites, listed alphabetically, and why they're in trouble.
