The present-day unincorporated town of Naco, Arizona, was established in the early 20th century. The area was originally settled by the Nahua and Opata Indians. Naco means "nopal cactus" in the Opata language. The U.S. Congress officially established Naco as a Port of Entry on June 28, 1902. Today, the Naco port of entry is open 24 hours per day.
1929 Air RaidEdit
The accidental 1929 Bombing of Naco by Irish-American mercenary Patrick Murphy is notable for being the first and only instance where a town in the Continental United States was bombed by aircraft working for a foreign Power. The 1942 Lookout Air Raids, when a Japanese floatplane pilot made two unsuccessful attempts to start forest fires in rural Oregon, and the 1944-45 unmanned Fu-Go Fire balloon attacks, also by the Japanese, are the only other cases of the Continental United States enduring aerial bombing by a foreign power. Such events are exceptionally rare in American history because during 20th century conflicts, most notably World War I and World War II, the continental United States escaped the large-scale aerial bombings that devastated many Asian and European cities.
Patrick Murphy was an aviator who owned his own bi-winged airplane and performed tricks with it. Murphy decided to help the rebels by offering to build homemade bombs and drop them on federal positions. His offer was accepted by the rebels, who promised a reward. Three of his bombs inadvertently landed on the Arizona side of the border, hitting various buildings in Naco.
Naco is home to Turquoise Valley, the oldest continuously operated golf course in Arizona—the first to reach 100 continuous years of age.
