The main campus of the University of West Florida is situated north of the city center. Pensacola is nicknamed "The City of Five Flags" due to the five governments that have flown flags over it during its history: the flags of Spain, France, Great Britain, the Confederate States of America, and the United States. Other nicknames include "World's Whitest Beaches" (due to the white sand prevalent along beaches in the Florida panhandle), "Cradle of Naval Aviation" (the National Museum of Naval Aviation is located at the Pensacola Naval Air Station, home of the legendary Blue Angels), "Western Gate to the Sunshine State," "America's First Settlement," "Emerald Coast," "Redneck Riviera," and "Red Snapper Capital of the World."
