Oya Historical Museum

This museum was opened in 1979 to show the history and mining operations of Oya stone. The museum is situated in an unusual setting of carved hills, whose arches and holes were formed in the search for the finest quality stone. The modern museum building contains various items related to Oya, the stone quarries, and their history. Visitors are allowed to go underground into an immense mined area.
This museum introduces the history of mining Ohya stone. The original quarry site underground is approximately 20,000m2 in area and 60m at the deepest point. The temperature here is constant at 8℃ throughout the year. The powerful, magical atmosphere here is truly overwhelming.
