Located in an abandoned underground reservoir, two delicate glass pyramids are the entrance signs. Natural light is virtually invisible in a reservoir once filled with 1.6 million liters of drinking water. Artificial lighting creates unique saturated colors for 50 glass artworks, unpolished granite walls and moist air contrasting strongly with fragile glass. Glass paintings are created by well-known artists. Please bring your warm coat when visiting! The maximum temperature in the museum is only 9 degrees Celsius.
