The Octagonal Barn, 1903. The College's first barn, built in 1889, was this octagonal structure. The addition was built in 1892. It served as the heart of the College's 180-acre farm until 1909, when construction of a new barn was completed. In its later years, the Octagonal Barn served the College as a horse barn until it burned in September 1924.
