The official search for a long-talked about Nazi train filled with gold and jewels, which may have been found in Poland, will begin this week.
The armoured train car, which disappeared in World War II, was reportedly found by two Polish men using ground-penetrating radar.
Experts will start using measuring equipment and detectors to begin a "non-invasive" search of the ground next week.
The searchers will not be allowed to dig, drill or introduce cameras into the ground.
There are concerns the train - which is believed to have gone missing near what is now the Polish city of Wroclaw as Soviet forces approached in 1945 - may be booby-trapped.
Polish media said the men who made the discovery want 10 percent of the value of the train's contents.
Rumours of two special Nazi trains that disappeared in the spring of 1945 have been circulating for years, capturing the imagination of countless treasure hunters.
