McKenna was named to honor Olivia Cleveland McKenna (Class of 1898) who, with her husband John, donated the funds to construct a social center and dormitory for women who were not affiliated with a campus sorority. It was such a charming, beautiful place that competition to live in it eventually became fierce.
A 1947 addition to the south was the last work in Boulder done from the designs of Charles Klauder. McKenna was converted to academic uses in 1962. Because it was built as a residence, its scale is comparable to that of a large private home. The terrace overlooking Varsity Lake is one of the campus treasures.
