Hutchinson Commons at the University of Chicago is modeled, nearly identically, on the hall of Christ Church, one of Oxford University's constituent colleges. The great room measures 115 feet by 40 feet, and was for many years the principal site of convocations of the university. It is located in Chicago's Hyde Park community and is currently used as a dining hall and lounge for university students and professors. The Harry Potter film series has used the original hall at Christ Church in each of its films, imparting a tourist interest in its American replicate.. The building was donated to the University by the banker, philanthropist and university trustee and treasurer Charles L. Hutchinson through a donation of $60,000 for the purpose.
