When Don Diego de Vargas re-settled Spanish rule in New Mexico, he made a promise to a statue of a virgin named La Conquistadora. He told her that if he could do this peacefully he would honor her with a fiesta. So every year since 1712 Santa Fe celebrates fiesta. It takes place in September the Friday after Labor Day. This is the oldest fiesta in the United States. In 2009 the Historic Santa Fe Foundation hosted a fiesta party at El Zaguan on Canyon Road where people were encouraged to dress in fiesta attire from the 1930's.
