Nazi gold train
The so-called Nazi gold train and Wałbrzych gold train concerns a local legend of a Nazi Germany-era train buried in a tunnel in Lower Silesia between Breslau (Wroclaw) and Waldenburg (Walbrzych) in May 1945 during the last days of World War II.
The area is now part of southwest Poland but was then in southeast Germany. Many searches for the train have been conducted since World War II, with no evidence of a train found. According to historians, it has never been proved the train existed.
A search from 2015–2018 received global media interest, culminating in a dig involving the Polish military, local and state officials, and privately funded individuals, but it turned up only a cavity filled by a natural ice formation. No evidence of World War II trains, tracks or tunnels was found in the area.
One of unfinished tunnels of Project Riese in the Owl Mountains
According to local legend, the armored train left Breslau (now Wrocław) laden with gold and other treasures. It was driven into a system of tunnels under the Owl Mountains that were part of an unfinished Nazi secret Project Riese (German for “giant”) near Wałbrzych. There it was supposedly buried in a warren of tunnels and mines created by the Nazis. The train is rumoured to hold up to 300 tonnes of gold, jewels, weapons, and masterpieces.
According to historians, it has never been proved that the train ever existed.
