Founded on May 2, 2008, by Madame Gloria Laureana S. Rosales, the Capitol University Museum of Three Cultures preserves the diverse heritage of Northern Mindanao's tri-people: Lowland Migrants, Indigenous Lumads, and the Maranao. The museum features five distinct spaces: Kasaysayan (regional history and archaeology), Posaka (antique Maranao heirlooms and artifacts), Rawari (indigenous and lowland culture), CU Art Gallery (rotating artwork exhibitions), and Memorabilia (honoring the university founders). Additionally, the Handumanan gift shop showcases authentic local crafts, woodcarvings, and textiles, fostering broader public appreciation for Mindanao's rich cultural identity and artistic traditions.
