Battle of Churubusco
In addition to the cannon, memorials and plaques placed outside the main monastery entrance in honor of the Battle of Churubusco, the second floor of the building itself is dedicated to the Mexican–American War and various other conflicts on Mexican soil between 1825 and 1916. This period in Mexican history is characterized by near-constant intervention by the governments of the United States, Spain and France in Mexico's internal affairs, ranging from political intrigue, diplomatic maneuvers and armed invasion to assert control over all or part of Mexico’s territory.
