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.

Yale Bowl

This place has held crowds of more than 70,000 on 20 occasions, most recently Nov. 19, 1983, for the 100th playing of the Yale-Harvard game. The scoreboard is notable because the time clock is arranged vertically instead of horizontally. (Photo courtesy Yale University)
