The Altar a la Patria, often called the Monumento a los Niños Héroes, stands at the entrance to Chapultepec Park in Mexico City. It honors the military cadets remembered for defending Chapultepec during the U.S. invasion of 1847.

For citizenship learners, the monument is tied to national defense, sacrifice, and the story of the Niños Héroes. It is one of the most recognizable patriotic monuments in the capital and connects directly to a frequently taught episode in Mexican history.
