The Obelisco a los Niños Héroes is a monument installed in Chapultepec, Mexico City. The cenotaph was created in 1881 by architect Ramón Rodríguez Arangoity, one of the cadets captured in the Battle of Chapultepec. The marble cenotaph was a typical nineteenth-century monument. This one lists the names of the six cadets, the Niños Héroes, killed in the fierce fighting in the Mexican–American War as military cadets defended as well as the 40 who survived the attack.
