Ponor Fortresses

These fortresses consist of three large circles of stone, which are 300 meters deep and more than 1 km large in diameter. The formation has 3 entrances and 4 balconies that stand on top of the Fortress. The cave has a 2 km long gallery crossed by a river, the largest underground river in the country. The access way starts with a forest road that leads to the first circle by passing a bump field which is parallel to Cetatilor Valley. The lateral Western wall (more than 150 meters high) presents a portal whose altitude is 74 meters high. A scree mosaic leads to the second entrance through an arcade. This second entrance is a circular abyss that has an altitude of 200 meters. The third entrance can be reached by climbing the metal stairs that are located to the left of the portal. The cracks on these sinkholes' walls allow the natural light to enter and the effect is impressive.
