English: When Hidalgo, defeated at the Bridge of Calderon, fled to Chihuahua, and was betrayed, tried, and shot, his head and those of his three companions, were brought here, and placed on four hooks still projecting from the four corners of the building near the roof; and there they remained until 1823, when the successful revolutionists took them down, and buried them, with the honors due to the memory of the first martyrs of Mexican Liberty. illustration from the book, "Our Sister Republic"
