Lithuanian Hillforts

These five hillforts, known locally as piliakalniai, represent the medieval defensive heritage of the Birštonas region along the Nemunas river loops. Ranging from the prominent Vytautas Hill to the strategic embankments at Paverkniai and Norkūnai, these archaeological sites served as vital fortifications against Teutonic raids between the 1st and 14th centuries. Each site features characteristic steep slopes and man-made earthworks that offer insights into the early military architecture and settlement patterns of the Grand Duchy of Lithuania.
