Ningcheng Temple, whose full name is Sanshan (Three Mountain) King Dutai Kaiji Ancestral Temple, is located in Ningpu Village, Changbin Township, Taitung County. It was the earliest Sanshan King Temple to be established in the east coast area. Ningcheng Temple was built a long time ago. It is presumed that it came with the early immigrants or the garrison during the Guangxu period of the Qing Dynasty.
During the Japanese occupation, the Ningcheng Temple, which was made with coral stones, was ordered to be abandoned. Local residents then moved the god and secretly worshiped under the big tree in the mountain. In the early post-war period, local residents first built thatched temples, and then initiated a proposal to build a temple, which is now the Ningcheng Temple. Every year, a festival is held to celebrate the birthday of Sanshan King.
