Undergraduate Admissions, Visitor Services, Human Resources, Advancement and Alumni Relations are located in the historic building at 101 Brattle Street. Named the Oliver Hastings House for the local builder who constructed the house in 1844, this Greek Revival style mansion is a Registered National Historic Landmark. The house was a significant stop on the Underground Railroad and, as noted by the U.S. Department of the Interior, "possesses exceptional value in commemorating or illustrating the history of the United States."
