The U of A (as opposed to rival ASU, in Tempe) is a major economic influence in Tucson, with a student population of more than 40,000. The land for the university was "donated" by a couple of gamblers and a saloon owner in 1891—their benevolence reputedly inspired by a bad hand of cards—and $25,000 of territorial money (Arizona was still a territory back then) was used to build Old Main, the original building, and to hire six faculty members. Money ran out before Old Main's roof was placed, but a few enlightened citizens pitched in funds to finish it. Most of the city's populace was less than enthusiastic about the institution. They were disgruntled when the 13th Territorial Legislature granted the University of Arizona to Tucson and awarded Phoenix what was considered the real prize: an insane asylum and a prison.
The university's flora is impressive—it represents a collection of plants from arid and semiarid regions around the world. An extremely rare mutated, or "crested," saguaro grows at the northeast corner of the Old Main building. The long, grassy mall in the heart of campus—itself once a vast cactus garden—sits atop a huge underground student activity center, and makes for a pleasant stroll on a balmy evening.
