The Danevirke was a long system of earthworks and walls across the base of the Jutland peninsula, in what is now the German state of Schleswig-Holstein, built to protect the southern border of the Danish kingdom. Tree-ring dating shows that it grew over several centuries, with major phases under early medieval kings such as Godfred in the early 9th century and Harald Bluetooth in the 10th century, and a brick wall added in the 12th century under Valdemar the Great. The barrier ran between marshes and the Schlei inlet, close to the trading town of Hedeby. It remained in use until the 19th century, when Danish troops abandoned it during the Second Schleswig War of 1864. UNESCO inscribed it together with Hedeby in 2018.
