The Earth Pyramids of Renon (Ritten), located on the plateau above Bolzano, are among the most spectacular geological formations in Europe. Formed around 25,000 years ago, they represent one of the most fascinating natural phenomena in South Tyrol and attract visitors all year round.
Where the Earth Pyramids of Renon are located
The earth pyramids are spread across three main areas of the Renon plateau:
- Longomoso and Monte di Mezzo, in the Rio Fosco valley;
- Soprabolzano, in the Rio Rivellone gorge;
- Auna di Sotto, in the Rio Gasterer valley.
Scenic trails and viewpoints allow visitors to admire these extraordinary formations in every season.
What the Earth Pyramids are
The earth pyramids are columns of moraine soil of glacial origin topped with large stones, known as “caps”. These stones protect the soil beneath from rain erosion, while the uncovered material is gradually washed away.
This process creates spectacular pinnacles, several meters high, shaped over thousands of years. When the stone on top falls, the pyramid loses its protection and slowly begins to erode.
