MacGregor Hall was the newest residence hall on campus, constructed in 1967, and named after Ruth MacGregor, a member of the class of 1910 who died on her way to serve with the Red Cross in France during World War I. MacGregor is notable for its bay windows and window seats, as well as its spacious rooms. Rooms facing Upper Lake have a beautiful view. MacGregor Hall also underwent renovations in the summer of 1999 with updated furniture, paint, and lighting in the common areas.
MacGregor Hall houses 132 students in single, double and triple rooms on five floors. MacGregor is the closest residence hall on campus to the nationally renowned Equestrian Center. It is also close to Kendall Sports and Dance Complex and many classrooms, as well as Willits-Hallowell Center, the main conference center on campus. Each floor has a balcony. MacGregor is adjacent to Ham Hall, and they share kitchen facilities, but have separate full-service dining halls.
