"Located at a depth of 70 meters (230 feet), this underground museum gives its visitors a unique opportunity to get themselves familiar with the nuts and bolts of mining engineering and see how snow-white gypsum is mined underground via tour around an underground gypsum mine. A part of the museum’s display is dedicated to history of mining engineering and developing of local gypsum deposit that began back in 1930’s." - Steven Perez from Bookmarklet
