An engineering marvel rusted away in the Louisiana wilderness: upon its completion in October 1958, the Union Tank Car Dome, located north of Baton Rouge, Louisiana, was the largest clear-span structure in the world. Based on the engineering principles of the visionary design scientist and philosopher Buckminster Fuller, this geodesic dome was, at 384 feet in diameter, the first large scale example of this building type.
"A Necessary Ruin" tells the history of the Union Tank Car Dome via interviews with architects, engineers, preservationists, media, and artists; animated sequences demonstrating the operation of the facility; and hundreds of rare photographs and video segments taken during the dome’s construction, decline, and demolition. The film was funded by a grant from the Graham Foundation for Advanced Studies in the Fine Arts.
