 Due to the land's terrain which resembles the highlands of South Korea, the area also became a training ground for Filipino soldiers prior to their deployment in the Korean War, thus earning the nickname "Mari-Korea".The late 1950s witnessed the growth of the area as the Tuasons decided to develop their landholdings into the Marikina Heights subdivision.Finally, on April 2, 1978, President Marcos signed the Presidential Decree 1489, declaring Marikina Heights as another barangay in Marikina's growing populace.
