Meteora is a rock formation in central Greece hosting one of the largest and most precipitously built complexes of Eastern Orthodox monasteries. The name translates to 'suspended in the air.' Starting in the 14th century, monks built 24 monasteries atop immense natural sandstone rock pillars to escape political instability. For centuries, the only way to reach these buildings was by climbing long ladders lashed together or being hauled up in a large net (a 'vrizoni') using a windlass. The monks famously said the ropes were replaced only 'when the Lord let them break.' Today, only six monasteries remain active. They are a UNESCO World Heritage site, recognized for their unique blend of natural wonder and daring Byzantine architecture.
