Public Auditorium - Pittsburgh, Pa.
The world's largest moveable dome, as seen from
the visitors observation promenade deck atop the
Gulf Building. This all-purpose sports arena, con-
vention hall and auditorium-theater, built at a cost
of 22-million dollars is one of America's engineering
wonders. The huge stainless steel roof, weighing
more than 3,653 tons, can be rolled back in two and
one-half minutes, for open-air events such as operet-
tas.
