Fancifully called Hawaii's Westminster Abbey, this historic house of worship 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. The upper gallery has an exhibit of paintings of the royal families. The graves of missionaries and of King Lunalilo are adjacent. Services in English and Hawaiian are held each Sunday, and the church members are exceptionally welcoming, greeting newcomers with lei; their affiliation is United Church of Christ. Although there are no guided tours, you can look around the church at no cost. www.kawaiahao.org. COST: Free. OPEN: Service in English and Hawaiian Sun. at 9 am.
