—The Architecture Puzzler

Created by Dave Guadagni


Architecture Puzzler #579

At the time the Dirigible Dock building was first built (1929), it was considered by some to enclose the largest unobstructed space in the world. Each end of the building had two doors measuring 202 feet (62 meters) high. Each door pivoted on a single pin at the top. Guess how these doors were designed to be pulled open. By teams of horses, a system of weights and pulleys, or with a locomotive?
