As the largest church in the Cook Islands, Ziona Tapu CICC Church stands proudly in the heart of Atiu. Built from coral limestone, this historic church features a unique three-storey bell tower, which visitors may climb with permission from the deacon. The Sunday service is a deeply spiritual experience, filled with powerful traditional hymns sung in harmony. A visit to Ziona Tapu offers both cultural and historical insight into the island’s strong faith and community spirit.
