Archaeologists Unearth 3700-Year-Old Wall in Poland (Mental Floss)

Scientists in Poland say they have made a surprising find at a well-excavated archaeological site in the southeast: the oldest stone wall ever discovered in the country. Dating to the Bronze Age, the wall, constructed of thick stone slabs, was found at the site of Zyndram’s Hill in Maszkowice beneath a settlement occupied throughout the first millennium BCE. The early stone wall is much older; based on radiocarbon dating of organic materials discovered with the architectural elements, the researchers estimate it dates to between 1750 BCE and 1690 BCE.
It’s a highly unusual find not only for Poland but for the wider region, the archaeologists said. "In the whole Central Europe there are only a dozen sites dated so early with more or less well-preserved stone fortifications,” Jagiellonian University researcher Marcin S. Przybyła said in a press statement. “At that time, the use of the stone as a building material was typical of the Mediterranean areas. In the temperate zone of Europe until the Middle Ages, fortifications were built with wood and clay."
The structure was built on a hilltop that had been flattened in antiquity to create an inhabitable plateau of about 1.2 acres. Clay from the hilltop was used to build a terrace on the eastern and northern slopes of the hill. The interior wall was constructed of large, 1.5-foot-long sandstone blocks held together with clay. It was fortified with a retaining wall forged from huge, 3-foot-long blocks. The wall was almost 460 feet long and nearly nine feet tall, and bordered by a trench about five feet deep. This formidable wall was both structural and defensive, surrounding the eastern and northern sections of the settlement.
