The Erzberg (ore mountain) consists of iron ore and is mined for hundreds of years. Until today it is the financial backbone of the area. According to legend it was discovered after a fantastic event.

A group of fishermen put a net into the nearby Leopoldsteiner See. After some time they pulled it out of the water and found a waterman in the net. Out of fear they tried to kill him, but the watermen asked them not to kill him. He offered them 100 years of gold, 1,000 years of silver, or never ending iron. The fishermen chose the iron and the waterman pointed to a mountain and vanished in the water. So the men discovered the Eisenberg, but the waterman went back into the Wassermannsloch and was never seen again.

The Wassermannsloch is a resurgence, the water is flowing out of a water filled cave named Neustücklgrotte. This cave is explored by the project Aquarius from the Verein für Höhlenkunde in Obersteier.
