Date de diffusion: Nov 07, 1968

Defying the force of gravity, man has strewn his structures across the earth. This program looks at some of them, from simple structures of column and beam to the vast Roman arched aqueducts, the stone needles of Milan's Gothic cathedral, cantilever and suspension bridges, and the miracles of graceful design wrought by modern precast concrete and reinforced steel.
