Immortalized through photographs, drawings, and stories, buildings that have been demolished or completely renovated exist in the realm known as “lost architecture.” Either for economic or aesthetic reasons, the old gets torn down for the new, often to the disdain of community members and architects. But demolished buildings tell a story about the ever-changing politics of preservation—and often, they tell it far better than buildings that were actually preserved ever could. As the architectural landscape continues to change around us, it is important to recognize our past, even if its traces have been eliminated from the physical world.
