Marvelous Bridges, Bulgaria


The Marvelous Bridges or Wonderful Bridges (BulgarianЧудни[те] мостовеChudni[te] mostove) are natural arches in the Rhodope Mountains of southern Bulgaria. They are located in the karst valley of the Erkyupriya River in the Western Rhodopes at 1,450 metres (4,760 ft) metres above sea level, at the foot of Persenk Peak
The "bridges" were formed by the erosive activity of the once larger Erkyupryia River. It transformed the marble clefts into a deep-water cave, the ceiling of which eroded through time and collapsed, possibly during an earthquake. Geologists suggest that the water carried the debris away. As a result, the two remaining bridge-shaped outcrops remained. The larger one (upstream) is 15 metres at its widest and 96 metres long, and shaped by three vaulted arches, the largest of which is 45 metres high and 40 metres wide.
