Watch | Bronze Age cemetery accidentally discovered in Poland

Archaeologists exploring the site of a planned highway in Poland unexpectedly found a Bronze Age cemetery with graves dating back 3,000 years. Near the village of Dunino in Poland's southwest Legnica region, archaeologists are planning to exploring the huge, almost perfectly preserved Bronze Age cemetery until late autumn. During development-led excavations in the area set aside for the planned S3 motorway, archaeologists were actually expecting to find remains from the battle of Katzbach. It was one of the most important engagements of the Napoleonic Wars, which took place in 1813 near Legnica. Instead, they came across the cemetery, which was in use between 3,300 and 2,800 years ago. The bodies were cremated before the remains were buried, explained Bartosz Karolczyk, one of the archaeologists working on the site. The team working on the site were able to deduce a lot about the status of the people buried there from the nature of their graves. Some of them must have been wealthy as their graves were equipped with dozens of secondary vessels, some of them with engraved decorations, which probably originally contained gifts for the dead such as food and jewelry, including pins, earrings and pendants. The archaeological team say they hope to learn more about the Lusatian culture.
