The basic elements of football started at Penn's Franklin Field, Harvard Stadium and the Yale Bowl three of our four oldest stadiums. Today they stand as monuments to the past, having essentially shaped college football and college athletics on the whole as we know them.
Built in 1914, the Yale Bowl spawned similar bowl-shaped stadiums, such as the Rose Bowl, Michigan Stadium and the Los Angeles Memorial Coliseum. Harvard Stadium, the Yale Bowl and the Rose Bowl are recognized as National Historic Landmarks. (Don Couture)
