The era of the raised hillfort along the Dukstos

Buivydų piliakalnis, tucked away in eastern Lithuania, lies on the banks of the Dūkštos river. Hidden by light forest cover, its three layers - old, middle, and modern - stand silent like a watchtower. Built on a ridge, the hillfort overlooks the river. The three layers are separated by deep trenches, with the middle and upper floors elevated roughly twenty meters above the lower one. The two lower floors measure eleven by twenty-five meters, while the upper floor is an oval, thirty-eight by twenty meters. The hillfort is ringed by former living quarters, now long abandoned. Archeological excavations in 1970 and 1979 revealed much more about this abandoned hillfort than could be covered in the sources. Who lived there, and what their lives were like, remains a mystery, a secret buried in the layers of time along with the structures themselves.
