Zyndram's Hill, Prehistoric hillfort summit in Maszkowice, Poland

Zyndram's Hill is an archaeological site with remains of stone fortifications built on an elevated location. The eastern and northern sides still show preserved walls, and visitors can see the partially reconstructed eastern gateway.

The site was inhabited over several millennia by different peoples, from early settlements through to the time of Celtic groups. Excavations in the second half of the 20th century uncovered remains spanning different prehistoric periods.

The name comes from a local legend, recorded around 1900, linking the hillfort to the medieval knight Zyndram of Maszkowice; excavations disproved this. Since 1910 a stone has marked the 500th anniversary of the Battle of Grunwald, celebrated on the summit, and a monument with later plaques stands there.

The hill rises 410 m above sea level, its plateau standing several dozen metres above the Łącko Basin and the Dunajec valley. Excavation trenches from the Jagiellonian University campaigns since 2010 lie on the plateau, so keep to the grass and earth tracks rather than crossing open dig areas. The ground beside the exposed wall end is loose stone and bare earth.

The stone fortifications rank among the oldest of their kind across all of Poland and show early building techniques that emerged elsewhere much later. This unusually early date makes the site particularly valuable to archaeologists.
