National Memorial
is a designation in the United States for a protected area that
commemorates a historic person or event. National memorials are
authorized by Congress. The memorial is often not located on a site
directly related to the subject and many, such as the
USS Arizona Memorial, do not have the word "national" in
their titles. The earliest and perhaps most recognizable National
Memorial is the uniquely designated
Washington Monument.
Most national memorials are owned and
administered by the
National Park Service, however some are administered by other
organizations but are considered affiliated areas of the National Park
Service. The owners of affiliated areas may request certain assistance
from that agency in maintaining the memorial.
