Where are the Halls of Montezuma located?

The Halls of Montezuma refers to the Chapultepec Castle located in Mexico City, Mexico. This site is historically significant, as it was the scene of a key battle during the U.S.-Mexican War in 1847. The phrase "Halls of Montezuma" is famously used in the Marine Corps hymn, symbolizing the bravery and sacrifices of Marines who fought in that conflict, representing a strong sense of pride and historical legacy in the Marine Corps tradition.

The other locations mentioned do not have the same historical significance in connection with the Marine Corps or the events of the U.S.-Mexican War. Havana, as the capital of Cuba, and San Juan, the capital of Puerto Rico, do not relate to the same context of Marine Corps history. Guadalajara is a major city in Mexico but is not connected to the specific historical events referred to by the term "Halls of Montezuma."
