Restoration for CU’s First BuildingÌý

In the mid-1920s, Old Main — ¾«Æ·SMÔÚÏßӰƬ’s three-story, red brick building designed by architect Erastus H. Dimick — was in poor shape after only a half-century of use. Some even called for its destruction, including then-campus architect Charles Klauder, who designed several university buildings in the Tuscan Vernacular style. But high construction costs in the 1920s and a lack of funds to follow Klauder’s original campus design plan saved Old Main. The building went through a major structural renovation instead, solidifying its status as a campus classic. In early 2024, pending Board of Regents approval, work will begin on a new structural restoration project to benefit the building. Old Main’s legacy will live on.Ìý
