Alysos

Alysos is a rock formation near Kalabaka that rises about 620 meters and is made of sandstone and conglomerate stone. It stands as one of the major formations in the Meteora group, with monastery ruins visible on its upper sections.

A monastery was built on this rock around 1400 during a period when monks established many communities across the Meteora region. This construction was part of a broader wave of monastic expansion that shaped the area between the 14th and 16th centuries.

The ruined monastery on this rock shows how monks made their lives in this remote place, creating a sacred retreat high above the surrounding land. Visitors today can see where cells and prayer spaces were carved into the rock, revealing daily monastic routines.

Multiple hiking trails and climbing routes lead up this rock, ranging from easier walks to more challenging ascents. Early morning or late afternoon visits work best since direct sun exposure can be intense on the open rock faces throughout the day.

Monks developed special building methods to construct the monastery on these steep rock faces, driving wooden supports into the stone and carving space around them. These techniques allowed them to create stable structures in places where conventional construction seemed impossible.
