Kawaiahao Church
Called Hawaii's Westminster Abbey, this historic house of worship was completed in 1842 and witnessed the coronations, weddings, and funerals of generations of Hawaiian royalty. Each of the building's 14,000 coral blocks was quarried from reefs offshore at depths of more than 20 feet and transported to this site. Interior woodwork was created from the forests of the Koolau Mountains, and the upper gallery displays paintings of the royal families. The graves of missionaries and of King Lunalilo are adjacent. Services in English, with songs and prayers in Hawaiian, are held each Sunday (Kawaiahao's affiliation is United Church of Christ). You can follow a free audio tour of the church and grounds or just look around by yourself.
