About Old Main (University of Arizona)
Old Main began life as the University of Arizona's School of Agriculture building, and it was the first building put up on the campus in Tucson. It ranks among the oldest surviving educational buildings in the western United States. In 1972 the building was listed in the National Register of Historic Places. Phoenix architect James Miller Creighton designed it, and construction began on October 27, 1887.
The $37,969 budget was spent before the roof was done. When university officials learned that agricultural schools could get federal loans, they renamed it the School of Agriculture instead of the School of Mines it was first meant to be. Federal funding paid for finishing it, and it opened for the university's first class on October 1, 1891. As the only building on campus, it held the classrooms, library, offices and dorms. In 1891, six faculty members taught 32 students.
A fountain in front of Old Main, the Alexander Berger Memorial Fountain, dates from 1919. Berger paid for it as a memorial to 13 University of Arizona students killed in the First World War, among them his nephew. Neglect left Old Main in disrepair, and the City of Tucson condemned it in 1938. The US Navy repaired it in 1942 for a Naval Indoctrination Training School in World War II, which averted demolition. Renovation of the whole building began in January 2013, and it was back in use ahead of the 2014-15 school year.
