Nazi gold fever has never been higher in the Polish city of Walbrzych following today's announcement that a tunnel—potentially containing a rumored Nazi train laden with 300 tons of gold, precious stones, and guns—was discovered nearby, CNBC reports. Officials describe the discovery as "a railway tunnel with a multi-level complex of underground corridors from the days of World War II." However, a lawyer working for the treasure-hunting duo who kicked off this whole train hunt last month attempted to temper excitement. He says the Nazi train is in the tunnel, but it is buried underground and doesn't hold anything of value other than some precious minerals, the AP reports. Wait, isn't gold a precious mineral?
CNBC reports Andreas Richter and Piotr Koper reportedly found the location of the train using a map from 1926 and announced it in mid-August, kicking off a mass influx of explorers, history buffs, and tourists to Walbrzych. The Polish army has been exploring the wooded area near the city since last week, and authorities are warning treasure hunters it could contain booby traps or weapons, according to the Los Angeles Times. There are also theories that the train, should it actually exist, could contain dangerous cargo or be fitted with explosives. Either way, the AP reports the army is working to clear trees and shrubs before it can properly explore the newly found tunnel. (Read more Nazi gold train stories.)
