Haili Church is the largest surviving wood-framed church built during the missionary period in Hawaii. It was built in 1854 on a stone foundation. The architecture is Greek Revival, a style brought over by the United Church of Christ missionaries that established the mission here in 1824. The first church was simple grass hut. The present building was listed on that National Register of Historic Places in 2002. The church continues to be serve as a lively place for the congregation to worship and socialize.
The missionaries—Asa Thurston, Artemis Bishop, Joseph Goodrich, and William Ellis—surveyed Hawaii to find possible locations for missions. Hilo, named Waiakea at the time, was one of them. Years of growth and evangelization increased the size of the congregation, prompting the construction of the present building.
