There are a lot of anniversarie s this year in the field of Historic Preservation. The first is the 110-year anniversary of the Antiquities Act that was signed by President Theodore Roosevelt in 1906, which enabled American presidents to create national monuments. Since the creation of the Antiquities Act, there are 121 areas known as national monuments. Ten years after the Antiquities Act, President Woodrow Wilson created the Department of the Interior to conserve national parks for their natural and historical significance. In those 100 years, The National Park Service has grown to 411 units. The National Park Service is celebrating its 100-year anniversary with its #FindYourPark campaign. Fifty years later in 1966, Lyndon B. Johnson signed the National Historic Preservation Act , which also created the National Register of Historic Places. In 1996, the Tennessee Civil War Heritage Area (managed by the CHP) was established to tell “the whole story of America’s greatest challenge, 1860-1875: the powerful stories of vicious warfare, the demands of the homefront and occupation, the freedom of emancipation, and the enduring legacies of Reconstruction.”
