The building was designed by Miller, Fullenwider and Dowling of Chicago, and completed in 1921. It is named for Brown Ayres (1856–1919), the university's 12th president. A detailed restoration was initiated in 2008.
The Gothic Revival structure rises 42.67m above its base, and currently houses the Mathematics department of the University of Tennessee.
