The US National Trust for Historic Preservation, another privately funded non-profit organization, began in 1949 with a handful of structures and has developed goals that provide "leadership, education, advocacy, and resources to save America's diverse historic places and revitalize our communities" according to the Trust's mission statement. In 1951 the Trust assumed responsibility for its first museum property, Woodlawn Plantation in northern Virginia. Twenty-eight sites in all have subsequently become part of the National Trust, representing the cultural diversity of American history. In New York City, the destruction of Pennsylvania Station in 1964 shocked many nationwide into supporting preservation. The 1960s proved advantageous with new laws and international agreements extending preservation "from ancient monuments to whole districts and buildings a few decades old." On an international level, the New York-based World Monuments Fund was founded in 1965 to preserve historic sites all over the world.
