・In 1986, a historical park was built, in which 20 Christian gravestones, which had lain separately in the Onoue, Rikino and Sakurababa areas of Arie Town, were gathered together.
・They are all plate-like flat gravestones placed horizontally on the ground.
・Located on a gentle hill situated above Arie Unzen Shrine, the park offers a panoramic view of Shimabara Bay and Yushima (Dango-jima), an island closely related to the Shimabara-Amakusa Rebellion.
