The original Old Mill was largely destroyed by fire in 1824. The blaze consumed much of the building. Despite this devastating setback, the university community rallied to rebuild. The replacement initially consisted of three separate buildings; they were joined in 1846. This act of resilience symbolized the nascent university's determination to persevere and grow. The rebuilt Old Mill, whose present appearance is defined by its 1882–1883 Gothic Revival remodeling, has since served as the academic heart of UVM for nearly two centuries, a testament to the community's unwavering commitment to education.
