The Diag

From left to right: the Engineering Building (1839–1922), the President’s House (1839), the Medical Building (1848–1914), South College (1849–1950), and Mason Hall (1841–1950)
The Diag (/ˈdaɪ.æɡ/ DY-ag) is the oldest area of the University of Michigan campus in Ann Arbor, Michigan. Originally referred to as the Diagonal Green, the Diag acquires its name from the multitude of sidewalks that traverse or border it in diagonal directions. Numerous historic buildings of the university are positioned in proximity to the Diag.
History
In April 2008, spring commencement ceremonies were held at The Diag, as Michigan Stadium was undergoing construction.[1] In April 2024, The Diag was one of the sites for the nationwide pro-Palestinian encampment.[2][3][4]
