The Pimeria Alta, the home of the "upper" or northern Pima Indians, was so named by the early Spanish settlers in Sonora.  The region stretched from the south at Hermosillo, Sonora, to the north at the Gila River in Arizona, and from the Sierra Madres and the San Pedro River on the east to the Gulf of California and the Colorado River to the west. 

Nogales is in the geographical center of the area. Housed in the Old Nogales City Hall, constructed in 1914, the museum provides information on the history of the Pimeria Alta and welcomes visitors to the border area.  The society was formed in 1948, when a group of 28 concerned citizens got together to preserve the rich and exciting history of the area. 

Since its inception, the mayor and city council of Nogales have supported the society, turning over the first floor and basement of the Old City Hall to PAHS for use as a museum in 1980.  ​They continue to provide funding for the museum's operations
​and refurbishing of the building.

Alma D. Ready was a driving force behind the creation of the Pimeria Alta Museum and its large research library. At her 2003 memorial service, the library was renamed the Alma D. Ready Library. In a special presentation, a beautiful stone plaque, created by Mexican artist Alonzo Villanueva, was mounted at the library entrance. It features a windmill taken from one of Ready’s photographs.

"Few can describe their lives much less write it as if a suspenseful novel yet with blunt, self effacing honesty. Alma Ready's MEMOIR is not a tell all, but she tells all, the unpretentious story of her life growing up in World War I, becoming a young woman in the raucous, roaring twenties, surviving the Great Depression, her four marriages of convenience and romance, producing four children and wrenchingly forced to surrender three, and growing up again in World War II to find her true calling as a photographer, historian and author." - Axel C.F. Holm, native Nogalian, noted historian and past president of the Pimeria Alta Museum and Historical Society.

The museum has a research library, rotating displays on the history of the region, archives of the Nogales International, Border Vidette, Oasis, and Nogales Daily Herald newspapers, three rare murals by renown bull fighter and artist Salvador Corona, and an extensive photography display on Camp Little, home of the Buffalo soldiers,  and life on the border. 

Visitors can tour the old jail cells, view the hand drawn and hand operated pumper fire truck known as "Able and Willing", and peruse displays that will lead to an appreciation of the long and fascinating prehistory and history of the area.
