A mountain keeps the movies.

The Packard Campus film vaults

Inside a former Federal Reserve continuity bunker in Virginia, the Library of Congress preserves millions of films, broadcasts, recordings, and the machinery needed to play them.

Saving a recording requires more than storing its content. The archive protects unstable originals, maintains obsolete playback systems, and creates durable digital copies that researchers can use.

The Packard Campus occupies 45 acres on Mount Pony near Culpeper, Virginia. Its storage facilities grew from an underground Federal Reserve Bank continuity-of-operations site decommissioned in 1993. Congress authorized a new national audiovisual conservation center in 1997, built through a partnership with the Packard Humanities Institute.

Most of the 415,000-square-foot complex sits underground beneath sod roofs. Nearly 90 miles of shelving hold sound and moving-image collections. Separate environments include below-freezing storage for film masters and 124 vaults built for nitrate film, an early motion-picture stock whose chemical instability and flammability demand careful isolation.

The laboratories can reproduce antique film, video, and audio formats. Preservation staff clean and inspect physical media, use compatible equipment to recover its signal, and create archival digital files. The system makes an additional copy of every archived file as it is preserved. A digital transfer improves access while the original object and its production history remain part of the collection.

The campus also records current broadcasts and maintains petabyte-scale digital storage. Researchers reach access copies through Library of Congress reading rooms in Washington, while a theater in Culpeper can project nitrate film and modern digital cinema. Public screenings reveal one result of the preservation work; the regular campus is not open for tours.
