I transferred to OU from UCO. The first college building I ever walked into was Old North at UCO. Opening in 1893, it is the oldest building of higher education in the state. It has had a reputation for being old and unstable; the building was first closed for safety issues in 1911, but it was renovated for continued use. In 2001, the building was closed for the same issues again. It was renovated during a $40 million project beginning in 2011 and officially reopened for classes again in 2017. I can’t find any updated interior pictures, but the style is very modern and mixes well with the design of the building.
