Muddled Secrets: Balnakalnis and Žydkapiai - Lithuania's Enigmatic Hillforts

Deep within Sudargo, these hidden hillforts have left researchers scratching their heads for eons, and while some answers continue to elude us, discoveries point towards Žydkapiai perhaps serving as a stepping stone for Balnakalnis. Balnakalnis, however, remains cloaked in mystery, with no clear evidence of cultural artifacts surfacing from its soil. Archaeological work at Balnakalnis has unearthed pottery dating from the 14th to 20th centuries, with reconstructions of the hillfort dating back to the 6th to 7th centuries. Each fort features walls as thick as 0.7 meters and ramparts standing 10 meters high. Measuring 20 meters wide, each fort ends in a ditch 4 meters deep. Both forts face the Nemunas at 70 degrees. Yet, why do these mystifying hillforts remain an unsolved riddle, and what secrets are they eternally mumbling into Lithuanian mud?
