7Meteora, Greece

Known for its otherworldly landscape, Meteora in central Greece is home to one of the most remarkable cliff-side locations on Earth.

The rock formations, towering over 400 meters (1,300 feet), house Eastern Orthodox monasteries that appear to cling to the rocks.

These monasteries, dating back to the 14th century, were built by monks seeking isolation and protection. Today, visitors can explore the monasteries and take in the panoramic views of the Pindus Mountains, creating a spiritual and serene experience.
