Constructed in 1929 during the presidency of Carlos Ibáñez del Campo, the Palace of Cerro Castillo was designed by Luis Browne and Manuel Valenzuela in the Spanish Colonial Revival style.

The palace was built on a hill whose land was attached to the nearby Callao Military Fort and occupancy of the new building began in 1930.
