“As people are already used to at Technotras, visiting this attraction is also experiential. Visitors try to cut the slate, touch the original tools, experience the absolute darkness underground, and subsequently the illumination with period lighting. The cold of the underground, with the sound of the constant dripping of water, awaits them and I believe that it will be an unforgettable experience,” Moravia-Silesia Deputy Governor Jan Krkoška (ANO) said, according to press reports.
