The story that haunts this land

Your quest begins in front of the Viking Museum Haithabu, opened in 1985, the starting point of the journey. Here you discover the foundations of Hedeby (Haithabu), a major Viking trading center located opposite Schleswig on the Schlei Fjord. This key archaeological site, now a UNESCO World Heritage site, was a cosmopolis where cultures mingled, essential for trade and the defense of Harald Bluetooth's kingdom. It was here, in this melting pot of civilizations, that the first tensions threatening the peace of the kingdom were felt, even before Sweyn Forkbeard rebelled against his father.

The path then leads you to the Nördliches Tor, the North Gate of Haithabu. Reconstructed, this 9th-century entrance gate was part of the fortifications encircling the 25-hectare Viking town. It was the main access for ships arriving from the Schlei and land caravans. It is along these ramparts that you examine the marks left by ancient defenders, searching for hidden symbols related to the conspiracy. The Danewerk, a Viking defensive rampart built around 737 AD to protect Hedeby from invasions, stretches for about 30 km across Schleswig-Holstein, and was a silent witness to the many passages through this gate.

Continuing your immersion, you walk along the Schlei, this 42 km coastal fjord connecting the Baltic Sea to the hinterland, bordering Hedeby and Schleswig. This waterway was essential for Viking trade in Hedeby, fostering its role as a cosmopolis. The waters of the Schlei have seen countless longships and merchant vessels pass by, carrying goods and secrets. You imagine the Viking ships whose remains were discovered at the port site, and understand the strategic importance of this waterway for kings like Harald Bluetooth, seeking to unify the region.

Your journey then takes you to the Königshügel, the King's Mound in Haithabu. This 10th-century Viking burial mound, one of the largest in Northern Europe at 14 meters high, is likely the tomb of a local chief or Viking king, excavated in the 19th century. It is located at the heart of the UNESCO site of Hedeby. By climbing this elevation, you get an overview of the reconstructed harbor, based on excavations showing a 200-meter-long quay from the 8th to 11th centuries. This Hafen was the center of Hedeby's international trade, with routes to Birka and Byzantium, a place where information and plots could easily circulate.

Concluding your exploration of the Hedeby and Schleswig sites, you have traced the route of the merchants and warriors who built the greatness of this Viking center. From the Nördliches Tor to the Königshügel, passing by the banks of the Schlei and the remains of the Danewerk, each stage has revealed a fragment of the tumultuous history of this crossroads in Schleswig-Holstein. You have not only thwarted the conspiracy threatening Harald Bluetooth, but you carry with you a deep understanding of the ingenuity and resilience of the Vikings, a heritage that continues to shape the region, listed on the "Viking Heritage Trail Schleswig-Holstein".
