This phenomenological study investigated the lived experiences of parishioners in conserving Spanish-era churches in Eastern Visayas, Region 8, Philippines. Through semi-structured interviews with participants chosen through purposive sampling, the study explored their perceptions, motivations, and challenges in preserving these historical landmarks. The theoretical framework integrated Cultural Heritage Theory, Collective Action Theory, and Social Constructivism to analyze the connection between faith, community engagement, and heritage conservation. The findings indicate that parishioners view their roles as spiritual and cultural responsibilities, though they face significant challenges including financial constraints, environmental threats, and declining youth participation. This study contributes to understanding the crucial role of community-driven conservation efforts in preserving religious heritage sites and offers recommendations for sustainable preservation strategies that balance historical authenticity with modern needs.
