Standing proudly on Ali'i Drive in Kailua-Kona, Moku'aikaua Church holds the distinction of being Hawaii's oldest Christian church, built in 1820 during a pivotal time in Hawaiian history. This remarkable Big Island landmark represents the intersection of Hawaiian culture and Western missionary influence, marking the beginning of Christianity's presence in the Hawaiian Islands. The church's unique construction showcases the resourcefulness of its builders, who used native lava rock held together with coral mortar made from burned coral and kukui nut oil. This traditional building technique has helped the structure withstand nearly two centuries of Big Island weather, creating a testament to both craftsmanship and faith. Visitors can explore this historic Kona Coast treasure through self-guided tours available daily, learning about the church's role in Hawaiian history and its continuing service to the community. The building's simple yet striking architecture reflects the practical needs of 19th-century missionaries while incorporating locally available materials that connect it to the volcanic landscape of Hawaii Island. Located in the heart of Kailua-Kona's historic district, Moku'aikaua Church offers an authentic glimpse into Hawaii's cultural transformation. The site provides educational displays about the church's founding and its significance to both Hawaiian and missionary history. Best of all, admission is completely free, making this historic gem accessible to all visitors exploring the Big Island's rich cultural heritage.
