4 km from the center of Piatra Neamt, Bâtca Doamnei is a height of about 45o meters, torn from the mountain range with steep slopes that descend to the lake of the same name. A modernized road rocky comes forward to her rocky foothills, then a wide path climbs gently up the ridge and brings us near the ruins of the Dacian fortress, one of the most interesting and ancient fortifications commented from Moldova, discovered by Constantin Matasa, in the year 1928 .
It is the oldest monument of the county, the fortress being mentioned by Ptolemy in the writings on the history of the Dacians. Vestiges of the Bâtca Doamnei occupies an area of nearly 20,000 square meters on the ridge height, determining two levels of living: one dating from the second century BC, the other from the period between first centuries BC and AC. The fortress known in the time of Burebista and Decebalus, a significant development. Archaeologists have discovered the stone wall that stretched like an irregular quadrilateral around the inside buildings, preserving it today, in the best conditions, only the southern side. But the most important building discovered is The Sanctuary made ​​of alignments of stone drums identicals with those found in the Dacian centers of Orastie Mountains. The sanctuaries were built only in areas with a high economic and military potential, which leads to the conclusion that the fortress from Bâtcă have a first class center features, giving it a great importance in the area of Eastern Carpathians. In support of this idea are the usual pottery, painted pottery, adornment objects, iron weapons and tools discovered here, proving a high level of economic and social development. Although not were preserved only remains of ancient buildings that no longer have monumental proportions and today are covered with dirth, a trip to the Citadel is an accessible experience. From the top of the peak Bâtca Doameni, you can admire the city, the lake, the monastery Bistrita, the surrounding mountain ridges, which, from a distance, it Ceahlăul dominates them with its greatness.
