This lovely sandstone arch has drawn tourists for decades to investigate the natural wonder. Tourists used to be able to climb on top of the arch and take pictures of the world below. However, in recent years, the Czech Republic has outlawed people from climbing to the zenith.

The reason? Erosion has caused the structure of the arch to become unstable. Simply put, the next person who climbs up might spell disaster for themselves and everyone standing below. Not to mention the people who haven’t had a chance to visit yet!
