The past, in motion.

Stories the photographs still tell

Each video starts from a real record — a plate from the Library of Congress, a forgotten world's fair, a building that no longer stands — and asks what it was, who built it, and what happened to it.

• Lost architectureThe grand civic buildings of the 1800s, many of them gone within a lifetime.
• World's fairsThe White City, the Paris expositions, and the cities built to be torn down.
• Fires, quakes & rebuildingSan Francisco 1906, Toronto 1904, Baltimore 1904 — before and after.
