NPS
The National Park Service (NPS) is an agency of the United States federal government headquartered at the Main Interior Building in Washington, D.C. that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The United States Congress created the agency on August 25, 1916, through the National Park Service Organic Act.
The NPS is under the United States Department of the Interior. The agency is charged with a dual role of preserving the ecological and historical integrity of the places entrusted to its management while also making them available and accessible for public use and enjoyment.
