Sand Origin
Piusa Open Pit
Random Sand Fact
In Estonia, sand mining created an underground landscape of vaults and pillars.
At Piusa, miners began digging for pure quartz sand for glassmaking in 1922. As the sand was removed, high galleries and massive pillars were left standing in the pale sandstone.
Today, the former mines are a visitor attraction. Estonia’s largest sand quarry lies just behind them, while thousands of bats hibernate deeper inside the tunnels.
