Arivaca Schoolhouse

The Arivaca Schoolhouse is a historic one-room school building located in the unincorporated community of Arivaca, in southern Pima County, Arizona. A small and simple structure made of locally manufactured mud adobe bricks, the Arivaca Schoolhouse was built in 1879 and is the oldest standing schoolhouse remaining in Arizona. It was added to the National Register of Historic Places on April 16, 2012, and is now used as a center for community activities.

The Arivaca Schoolhouse was built by Don Pedro Aguirre, an Arizona pioneer that had come to the United States from his native Chihuahua, Mexico, in the 1850s. In 1868, Aguirre opened a stagecoach stop for his freighting business near Arivaca and eventually became one of the leading citizens of the community durings its period of development in the 1870s. In 1879, Aquirre built the Arivaca Schoolhouse for his own children and those of his employees, at his own expense. The building is a simple one-room rectangular structure with a stone foundation, stuccoed adobe walls and a wooden roof covered in tin. The Arivaca School District was established on April 8, 1879.

The schoolhouse was in use for over seventy years from its construction in 1879 to its closing in 1953.
