Bronzezeitliche Befestigung bei Bernstorf, Bronze Age archaeological site near Kranzberg, Germany.

The Bronze Age fortification near Bernstorf is an archaeological site on the Bernstorfer Hill in Bavaria, about 1.4 km north of Kranzberg. It covered roughly 13 hectares and was enclosed by a wood-earth wall over 1.6 km long. Three quarters of the settlement area have been removed by gravel extraction.

The rampart was built around 1360 BC and enclosed a settlement of nearly 13 hectares. Slag finds show the blaze reached about 1300 °C, suggesting the site was deliberately burned down. Local historian Josef Wenzl found the earthworks in 1904, but their date and scale were only recognised around 2000.

People here maintained connections to distant cultures, as shown by gold finds and amber objects bearing inscriptions. These items suggest that residents traded with Mediterranean regions and lands to the east.

Visitors should know that large portions of the original fortification were destroyed by gravel extraction during the later decades of the 20th century. The site today is a research location, and information panels help explain the surviving structures.

Some of the site's most valuable finds, including a gold diadem and amber artifacts bearing inscriptions, came under scientific scrutiny in recent decades. Researchers debate the authenticity of these items and their true origins, making the excavations intriguing to this day.
