Aerial view of Bar Harbor. Bar Harbor was first named the Town of Eden in 1796, then renamed Bar Harbor in 1918. Bar Island is located in the foreground and the mountains of Acadia National Park are in the background. George B. Dorr and Charles W. Eliot, and later John D. Rockefeller Jr., all worked to create a National Park. The park was named Lafayette National Park in 1919 and then Acadia National Park in 1929.
