On top of these large pillars of rock site Greek Orthodox monasteries that were built more than half a century ago. They chose to build on top of these monolithic pillars, because they thought it would bring them close to God, and when I went up to these monasteries, you understand where they're coming from. Being that high up, looking at the town of Kalambaka humbles you. These huge pillars of rock leave you in a state of awe inspired helplessness. The view is mystical.
