The old underground quarry known as “the unknown space”
The old mining site of Utsunomiya’s specialty, Oya Stone, has now been turned into a historical museum. The exhibition features the long history of the mining since the 17th century, with many documents on display. The underground cavern, covering 20,000 sq. metres, is large enough to fit a baseball field. With a fantastic atmosphere reminding visitors of the ruins of Ancient Rome, the cavern is widely utilized as a location for shooting movies and music videos, as a venue such as concert hall, theatre, Noh theatre, business functions and wedding receptions.
