Important Facts About the City of Seven Wonders
The City’s History
On July 4, 1876, a group of lumberjacks were celebrating Independence Day. They nailed a U.S. flag to the top of a pine tree and called it Flagstaff. By 1928, Flagstaff was officially incorporated as a city and is also often referred to as the
“City of Seven Wonders.”
The Home of Pluto
As a dark sky city, Flagstaff is the home of two major observatories, one of which is Lowell Observatory where Pluto was discovered in 1955. To continue achieving multiple missions in astrophysics, the institution has partnered with the nearby United States Naval Observatory and the Naval Research Laboratory.
