Zrinski Mine Opened in the 16th Century _______________ In the 16th century, galena, which contained silver as an admixture, was found in the Ruadrski Vrt area. Soon after, mining began on Medvednica, and hardworking miners worked 10 to 12 hours a day – using hammers, wedges, picks and shovels. The Zrinski family stopped mining in the mid-17th century because they were not satisfied with the results – a ton of galena had to be mined for half a kilogram of silver. Until 2004, the mine was abandoned and inhabited by underground creatures – when it was finally restored.
