The Museum of the Revolution in the Border occupies the former Customs House (Aduana Fronteriza), a handsome 19th-century building a block from the river. The museum covers the Mexican Revolution of 1910–1920 with a specific focus on Juárez's role — which was pivotal: the 1911 Battle of Juárez was the turning point that brought down Porfirio Díaz, and the peace treaty that ended his regime was signed in this building.
The exhibitions are in Spanish but the historical artefacts — photographs, weapons, documents, and personal effects of revolutionary figures — communicate across the language barrier. Pancho Villa is the central figure in much of the display, partly because of his fame, partly because he used Juárez as a base during the revolution. Admission is free or very cheap; the building itself is worth seeing for its architecture.
