How monks built a sanctuary atop sixty-million-year-old stone columns in central Greece
In short: Perched 373 metres above the Pineios Valley, the Monastery of Varlaam is a testament to human endurance and isolation. Founded in 1517, this site is one of the few remaining active monasteries in the Meteora region, where religious communities have sought refuge on perilous, towering rock formations for centuries.
The Meteora region, located near the town of Kalambaka, is defined by its dramatic geological history. The towering cliffs, which rise over 400 metres, are composed of sandstone and conglomerate formations. These structures were shaped by fluvial erosion and seismic activity during the Pliocene epoch, creating what are often called heavenly columns. Chemical analysis suggests these formations are approximately 60 million years old, originating from sediments once submerged in an ancient inland sea.
Monastic life in this region began long before the construction of the current buildings. Hermitages were established at the base of these cliffs as early as the 11th century. By the 14th century, political instability in the region drove monks to seek the safety of the heights. The titular emperor of Serbs and Greeks, John Uroš, played a pivotal role in this era, becoming a monk and actively endowing and rebuilding monasteries to support the growing religious community.
At their peak by the end of the 15th century, there were 24 monasteries scattered across the cliffs. While many have since fallen into disuse, the site remains a significant cultural landmark. In 1988, the six remaining monasteries, including Varlaam, were inscribed on the UNESCO World Heritage List. As of December 2025, Varlaam, Holy Trinity, St. Stephen, and the Great Meteoron remain occupied, while the Rousanou and St. Nicholas Anapafsas monasteries are preserved as part of the protected site.
