If you couldn’t make it down to D.C. last month for the Environmental Film Fest, it’s still not too late to catch one of the entries, A Necessary Ruin. The movie tells the story of the untimely destruction of Buckminster Fuller’s Union Tank Car Dome, a piece of railroad infrastructure that was the largest clear-span structure when it was completed in 1958 before being summarily destroyed three years ago. Its epic story will be told tomorrow nightnext Friday at the Center for Architecture, followed by a lively discussion with Jonathan Marvel, all part of the current show, Modernism at Risk. You can watch the trailer after the jump.
