The World Monument Fund was developed to call attention to cultural sites and landmarks who’s existence is threatened by human activities.

This year’s list of the 100 most endangered sites includes 59 countries. The United States is home to more listed sites than any other country at seven, including types of development such as “Main Street Modern” public buildings that symbolized progress after World War II. There are six sites listed in Peru and five each in India and Turkey.

The entire list is updated every two years.
