In the early 1980s, the National Park Service conducted an evaluation of Wake Island to determine if the World War II (WWII) cultural resources remaining on Wake, Wilkes and Peale were of national historical significance. As a result of this survey, Wake Island was designated as a National Historic Landmark (NHL) on September 16, 1985, helping to preserve sites and artifacts on the atoll associated with WWII in the Pacific and the transpacific aviation era prior to the war. As a National Historic Landmark, Wake Island was also included in the National Register of Historic Places.
