The downtown Phoenix campus of Arizona State University is growing like crazy but three of the buildings that have been integrated into the campus are historical buildings that are listed on the Register of National Historic places. The three buildings used to be home of Phoenix Union High School. The school closed in 1982 and the buildings housed offices for a period of time. In 2007, the University of Arizona bought and refurbished the buildings to become part of the school's College of Medicine. You might notice that distinctive red, white and blue "A" on the sign to the left of the building above. This building was once the High School's Sciences Hall.
This building housed the auditorium.
And this building was listed as the domestic arts building.
So even though ASU and UA are friendly rivals, the two are sharing space on the downtown campus. You can see the initials for both schools on the side of this building.
