#12: Pravcicka Brana
Pravcicka Brana, Europe’s grandest natural sandstone arch, is a breathtaking marvel and the Czech Republic’s premier attraction. Its immense size and natural beauty draw countless visitors. However, to preserve this geological wonder, access has been restricted since 1982.

Excessive foot traffic threatened to erode the delicate sandstone, prompting authorities to protect it by closing the arch to the public. Today, admirers must appreciate Pravcicka Brana from a distance, ensuring its preservation for future generations.
