The Olympic National Park Headquarters Historic District overlooks Port Angeles, Washington from Peabody Heights, consisting of 6 contributing buildings built in 1940–44, 8 contributing structures and 17 non-contributing properties that act as the administrative headquarters for Olympic National Park.

The contributing structures were built using locally obtained native materials in a late interpretation of the National Park Service Rustic style.

The irregularly shaped two-story building is similar in style and materials to the headquarters.
