The Earth Pyramids of Trentino Alto Adige

The land pyramids of Trentino, also known as earth pyramids, are a remarkable natural phenomenon found in the region. These unique formations resemble towering pillars or pyramids, with large boulders balancing on top of narrow clay columns. They are the result of centuries of erosion caused by wind and water, creating an awe-inspiring landscape.

There are several remarkable and easily accessible earth pyramid formations that are worth visiting. Some of the most well-known and breathtaking ones include:

  • The Renon Earth Pyramids in Renon, situated above Bolzano. These pyramids are divided into three distinct groups near the villages of Collalbo, Soprabolzano, and Auna di Sotto.
  • The Plata Earth Pyramids, located near Perca in the Val Pusteria.

Formation of Earth Pyramids

The earth pyramids in Trentino are striking structures formed by morainic cones topped with large rocks. They are composed of fluvio-glacial moraine clay, remnants of the main glacier in Val Isarco and local secondary glaciers. These unique geological formations exhibit cohesiveness and compactness in dry conditions, but when exposed to rainfall, they lose stability and crumble, resulting in 10-15 meter high slopes.

The rocks firmly adhere to the clay, creating a protective barrier against rain. However, with each precipitation, the exposed material undergoes erosion and is carried downstream, gradually revealing the majestic earth pyramids. The formation of these pyramids is influenced by various factors, making it challenging to determine their exact formation time. Similarly, accurately determining the age and potential height of the pyramids is nearly impossible. However, it is evident that the most stunning and largest earth pyramids have taken shape over thousands of years.

The lifecycle of an earth pyramid is relatively short-lived once the protective “cap” at its peak falls off. Unprotected from the elements, the exposed material gradually diminishes with each rainfall, causing the column to shrink. However, as one pyramid disappears, a new one simultaneously emerges on the slope, perpetuating the cycle of these fascinating natural phenomena.

Hearth Pyramids of Perca

These clay column formations tower above, topped by large boulders, leaving a trail of fascination for visitors. And it’s no wonder, considering that the earth pyramids of Perca, located near the Rieserferner-Ahrn Nature Park, are considered the most significant formation in the Val Pusteria. However, the pyramids of Perca are not the only ones in the region. There are also other earth pyramids, such as those in Terento, and smaller ones in the Val di Fana near Dobbiaco.

To reach the starting point for the earth pyramids, you have a couple of transportation options. If you prefer to travel by car, you can drive from Perca and follow the road to Vila di Sopra or Oberwielenbach. Continue in the direction of Plata, and you will reach your destination. Alternatively, you can take the bus or train to Perca and then transfer to the Citybus (stop at Casa Culturale) that will take you to Vila di Sopra – San Nicolò Church. From there, you can continue on foot to reach the pyramids.
