Chudnite Mostove (The magnificent Bridges) a rock phenomenon situated near the Zabardo village West Rhodope mountain,Bulgaria. The "bridges" were shaped by the destructive activity of the once high-water river. It transformed the marble clefts into a deep water cave, the ceiling of which whittled up through time and collapsed, allegedly during an earthquake. Geologists presume that the water carried the debris away. As a result, the two left over bridge-shaped boulders remained. The adjacent area is timbered by century-old conifers, largely spruces. In the past the bridges had been one entire cave, formed under the erosive activity of the river waters. Parts of it were collapsing with time, forming majestic marble bridges. The huge bridge is about fifteen meters wide in its wider parts and almost hundred meters long. It consists of three arches, as the largest one is 45 meters high and 40 meters wide. The small bridge is at a distance of 200 meters from the large one along the river current. It is blocked, 60 meters long, with total height of 50 meters, and the height of the arch is 30 meters. There is also a really small third bridge after it, which is a ponor cave, in which the waters of Erkyupriya River disappear, to become visible again on the surface 3 kilometers farther.
