The Pimeria Alta Museum is housed in the Old Nogales City Hall which was constructed in 1914. The museum provides information on the history of the Pimeria Alta and welcomes visitors to the border area. The Pimeria Alta Historical Society (PAHS) 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 inauguration, 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.
