The Wall/El Muro: What Is a Border Wall? examines the U.S./Mexico border from its physical presence to the conceptual role it plays in defining our nation. The exhibition looks at examples of borders around the world, the history of the U.S./Mexico border, and current conditions that define the border experience. Through physical artifacts, images, texts, sound pieces, and data visualizations, the exhibition design strives to help visitors see how the physical border wall makes real—and internationally consequential—something that is otherwise relatively symbolic.
