Historic preservation is the physical rehabilitation of historical buildings and neighborhoods. The United States began its campaign for preservation in the 1960s. Historic preservation has been a concern for the United States for a long time. In 1966, the federal government established the “National Historic Preservation Act”. The purpose of the act was to insure that the cultural and historical foundations of the country were preserved in the face of development that was increasingly destroying landmarks that were crucial to the future development of the country. Congress found that the cultural and historical basis of the nation needed to be preserved to give a sense of “orientation” to the American people. The goals of the act were specific, calling for any measure needed, including financial support, to maintain a balance between the current society and prehistoric and historic resources.
