Pennsylvania Avenue, sometimes called "America's Main Street," is being listed among the nation's endangered landscapes because of neglect and deferred maintenance by the National Park Service.

Officials at the Nasher Sculpture Center reacted with surprise Wednesday to the Washington-based Cultural Landscape Foundation releasing its list of “endangered landscapes,” which included the Nasher sculpture garden, whose damage the organization blamed on the glare from Museum Tower.

The sculpture installation called “Green Acres” will remain to usher visitors and employees into the state Department of Environmental Protection building in Trenton.
