Before construction, the land on which it is located belonged to the nearby Park of the Exposition before the area between 28 de Julio Avenue and Larrabure y Unanue Street was built over. In 1926 construction was commenced as ordered by the president Augusto B. Leguía. It was named of the Reserve in honor of the last soldiers who fought in the Battle of San Juan and Chorrillos, and the Battle of Miraflores. The park was completed in 1929.
