A vast neoclassical granary built in the 1790s to store the wheat and corn that fed the silver miners, now the Regional Museum of Guanajuato. The collection covers pre-Hispanic ceramics from the surrounding state, the colonial period, and an extensive section on the War of Independence — at the corners of the building, iron cages still mark where the Spanish hung the severed heads of the captured insurgent leaders Hidalgo, Allende, Aldama, and Jiménez for ten years as a warning.
The museum is worth two hours. The murals on the staircase by José Chávez Morado, telling the story of the city's silver and revolution, are among the finest in Mexico.
