It is located 4 km from Costești, at an altitude of 705 m, and it is included in the UNESCO World Cultural Heritage. The upper area of the hill was worked by the Dacians into a relatively flat area of about 6000 m2. The fortress was built in two stages, the first consisting in a relatively trapezoidal enclosure, with strong stone walls and four square towers, the entrance being made through the South-Western tower. At the same time, two other towers were built, one inside and one outside the fortification. During the 1st century A.D., the fortress was extended westwards, including the exterior tower. Square towers were erected on the terraces; their “ground floor” was build of limestone blocks, using a technique similar to that used for the fortress walls. The towers were most likely used as aristocratic residences, but they also represented important surveillance points meant to protect the access to the fortress. The traces of some square temples observing the pattern of column alignments were discovered relatively far from the fortified enclosure. Near the fortress, on the hill slope, there is a paralellipipedic water tank, whose upper part was dome-shaped and whose walls were covered in an insulating layer of lime, sand and crushed brick. The fortress was destroyed during the second war against Trojan, in 105 - 106 A.D..
