Marcelinian civilization, according to old Municipal documents, started at the peak of the beautiful Vega Hill in the heart of an idyllic and luxuriant Zambales jungle during the pre-Hispanic settlers from the Ilocos Region led by the old Corpuses, Udans, Ragadios, Raguinis, Rabanes and Fabunans. With courage, hard work and perseverance, these Marcelinian forefathers harnessed the untouched wilderness of Vegal Hill and its immediate surroundings and slowly converted the area into a pulsating and vibrant community nurtured by the abundant natural yield of what was once an untamed wildlife.
