The columns lining the inner seating area of Harvard Stadium indicate a Roman Tuscan style. The Colosseum, on the other hand, contains Doric, Ionic, and Corinthian styles, making it a great example of classical styles imitating older styles in much the same way neoclassical imitates classical architecture.
    The hallways of both the Harvard Stadium and the Colosseum are lined with a series of arches. The Colloseum was built curved all the way around, whereas Harvard Stadium is curved along one side. There are long straight walls connecting to that semicircular end of the structure. This greatly affects the interior lighting in the buildings. While in the Colloseum each arch is lit differently due to slight changes in angle to the sun, the straight hallway in Harvard Stadium allows each arch to be lit nearly identically since they all face the sun at the same angle.
    The ceilings of the two structures differ in that the Colloseum has arched ceilings as opposed to the flat ceiling of the Harvard Stadium hallway.
