Pravcicka Brana – Czech Republic
The Pravcicka brana is the narrow rock arch formation seen above. It’s located in Bohemian Switzerland in Czech Republic. The arch stands 16 meters above ground, is 26.5 meters long, and is the largest natural sandstone arch in Europe. In 1982, the government restricted public access to the site due to erosion, which was hastening due to so many visitors. Geologists believe the arch will eventually collapse on its own.
