I love Bing because of the marvelous pictures and the interesting facts they put up every day. And now I love them even more because they put up the amazing Belogradchik rocks!
Belogradchik is a town in Northwestern Bulgaria, near the city of Vidin, between the Danube and the Serbian border. There is an observatory in the city, amazing rocks in the outskirts, and numerous caves in the area.
The Belogradchik Rocks are fairytale-like rock formations with curious shapes: one can clearly see outlines of the Madonna, the Shepherd, the Horse Rider, the Eagle, the Schoolgirl, and Adam and Eve.
In 2007, the Belogradchik Rocks were semi-finalist in the New 7 Wonders of Nature contest!
My favorite site around Belogradchik is the ancient fortress Kaleto . It was built during the 2nd-3rd century by the Romans who guarded the important roads there. It was later used by the Byzantine and Bulgarian soldiers as a defense fortress.
The Rocks were formed from the clay, silt, and sand deposits on the bottom of an ancient sea, which rose with the rise of the Balkan mountain range. Once dry, the rocks were eroded by temperature fluctuations, water and winds for millions of years. The red color comes from the iron in the sediment. Erosion carved over 100 caves in the nearby rocks.
The most famous cave in the region is the Magura. It is 3000m deep. What is unique about it, beside its size and beautiful stalactites, stalagmites, and chambers, are the over 700 cave drawings made by humans from the Bronze Age: over 30,000 years ago! Drawn with red clay and bat guano, those illustrate hunting and festive rituals.
