Perote Castle (Castillo de Perote).
This old structure, built by the Spanish, was used by both the Spanishand Mexican governments as a prison. Among its more illustrious occupantswere the Texians captured during the ill-fated Texian-Santa Fe Expeditionof 1843. During the U.S. occupation, 1847-1848, it was used as ahospital. As a result, the area surrounding the moat is littered with theforgotten graves of hundreds, perhaps thousands of U.S. soldiers. Thecastle is presently being used as a prison.
