Gollenstein

The Gollenstein is a single standing sandstone menhir erected roughly 4,000 years ago during the late Neolithic to early Bronze Age, standing 6.58 metres tall and recognized as the largest standing stone in Central Europe. Its original purpose is not definitively established, though archaeologists generally interpret such menhirs in the region as markers tied to burial sites, territorial boundaries, or ceremonial gathering points, and similar smaller stones have been found elsewhere in the Bliesgau area. In 1939, with war against France anticipated, German army engineers toppled and broke the stone out of concern that its height on high ground near Blieskastel could serve as a landmark for French artillery targeting across the nearby border. The broken pieces lay on the ground for over a decade until the stone was re-erected and restored in 1951 using its recovered fragments, a repair still visible as fracture lines across its surface. The site preserves no built structure beyond the stone itself, standing in an open field on the Blieskasteler Berg, and functions today as an archaeological monument protected under German heritage law. Its scale and prehistoric age make it a rare survival from a period for which the region otherwise has little standing physical evidence, predating the Roman and Frankish sites more commonly found across Saarland.
