Today the tower is the only preserved town gate of Leoben and the landmark of the town.
In the 13th century it was renovated by Peter Carlone in 1616 and after severe damage by an earthquake in 1794 it was provided with the mushroom-shaped roof, to which its popular name "Schwammerlturm" goes back.
The verse inscription with historical references was added in 1845 on the occasion of a restoration by the Upper Styrian painter Johann Max Tendler, the addition was written later with a reference to recent history by Josef Freudenthaler.
Today the "Schwammerlturm" is accessible again and offers a wonderful view of the city and its surroundings.
