THE GREAT COURT OF
THE HALL OF SCIENCE
This court covers an area of three acres. Here,
visitors gather for festival ceremonies and other
special events. Speakers address them from a
uniquely constructed rostrum extending into the
center of the court from the terrace. Within the
huge steel frame behind the rostrum hangs the
electrical chart which was used in demonstrating
how the different Observatories made contact with
the star Arcturus, when its rays turned on the
lights of the Exposition,
Chicago World's Fair, 1933
