The oldest historical monument in Piatra Neamt is the Dacian Fortress on Mount Bâtca Doamnei located in the southwestern part of the city on the ridge of a spur, at an altitude of 457 m. The place where it was built is the last extension to the north of Mount Doamnei , from where the fortress came out towards the river Bistrita like a bastion that closed this valley, protected by the almost vertical slopes from the east. Access to the fortress was through a narrow saddle, which climbed gently to the Batca Doamnei, just like a bridge.
Considered one of the most interesting and commented ancient fortifications in Moldova, this powerful Dacian fortress still hides many mysteries waiting to be discovered. Although there were several periods in which systematic archaeological excavations were made that put us in front of the existence of a settlement belonging to the Eneolithic (Cucuteni A), the Bronze Age (Monteoru culture), Dacian fortress (1st century AD - 1st century BC). AD, and a feudal settlement (12th century), the ruins of the fortress are still accessible only archaeologically.
