Alhóndiga de Granaditas
Previously, this 18th-century grain-storage facility served as a jail under Emperor Maximilian and as a fortress during the War of Independence, where El Pípila helped the revolutionaries overcome the royalists. The hooks on which the Spanish Royalists hung the severed heads of Father Hidalgo, Ignacio Allende, and two other independence leaders still dangle on the exterior of this massive stone structure. It's now a state museum with exhibits on history, archaeology, and crafts.
