The Natural Geosite of the Calanchi of Chiusure

Exploring this breathtaking landscape, dominated by the Calanchi, will lead you to admire the immense power and beauty of nature, leaving you in awe of such a marvel!

This is a place that tells an ancient and profound story, where human history intertwines with the force of nature.

The Natural Geosite of the Calanchi of Chiusure and Monte Oliveto Maggiore is composed of clays and sands from the Pliocene epoch, dating back 4 million years.

In this extraordinary environment, nature has sculpted an intricate system of deep ravines, some stretching for dozens of meters, gradually retreating uphill and forming a fascinating and complex hydrological network.

These sharp ridges, as thin as knife blades, alternate with softer shapes on the clay, creating the distinctive calanchi formations that encircle the village of Chiusure.

Standing on the panoramic terrace of Chiusure is an experience that goes beyond a simple scenic view. It is an intimate encounter with the power of nature and the resilience of humankind. From here, your gaze sweeps over the majestic formations of the calanchi, witnessing the relentless strength of the elements. And yet, as you admire this imposing scene, you also sense the fragility of humans, small and vulnerable in the face of such power.

The people of Chiusure know this reality well. They live in a land that challenges them daily with its sheer grandeur, perched with determination on these rugged landscapes. The history of the village is a testament to this struggle: in the 15th century, the medieval castle that once dominated the area collapsed into the cliffs, defeated by nature’s might. But the villagers did not surrender. With courage and determination, they rebuilt their fortress on an adjacent promontory, giving birth to the village we see today.

Every corner of Chiusure tells this story of resilience and adaptation, and the panoramic terrace is its perfect symbol: a place where the beauty and power of nature meet the indomitable spirit of humankind, in a timeless dialogue.

A notable historical account comes from Pope Pius II, who visited the Abbey of Monte Oliveto Maggiore in September 1462. When he observed the landscape of the Calanchi, their wild and imposing nature left him utterly speechless. In his Commentaries, the Pope vividly describes the deep impression these formations made on him:

"If you ask what shape the hill housing the Abbey of Monte Oliveto Maggiore takes, observe the leaf of a chestnut tree. Precipices of crumbling rock, deep chasms (whose sight inspires horror and dread) block access from all sides, save for a narrow strip of land, at the entrance of which stands a solid defensive tower…"

Pius II’s words paint a striking vision, where nature appears both majestic and impenetrable—a place that commands reverential fear. Reading his words allows us to immerse ourselves in a past where humanity confronted the untamed force of the land daily. This landscape does not just enchant; it challenges and dominates all who behold it!

Straying off marked trails and attempting to explore the calanchi formations is not only ill-advised—it is extremely dangerous. The walls of the calanchi are unstable, their material crumbles easily, and the slopes can be incredibly steep, sometimes even vertical.

Let’s admire this incredible Geosite from the many panoramic viewpoints that dot the area!
