What made the 2014 World Monument Watch List and why?

They are under threat from war, the environment, economic development and more: 67 sites in 41 countries on the 2014 World Monument Watch, released Tuesday. PBS NewsHour correspondent Jeffrey Brown spoke with Bonnie Burnham, president of the World Monuments Fund, a non-profit organization that issues the annual list — which includes the Italian city of Venice, Myanmar’s capital city of Naypyidaw and St. Louis’ famous Gateway Arch — and that is dedicated to preserving endangered historic, architectural and cultural sites.
