One of the highlights of the Oya Stone Quarry Site and Museum is the tour of the 20,000 square meter underground quarry site. As you descend the stairs, a huge underground space appears before you. Here, you can see the remains of the quarry on the ceiling and walls, as well as dioramas that recreate the tools and scenes used in quarrying. The vast space of the quarry site is full of power, giving you an experience as if you were in the depths of the earth!
