Schleswig
Schleswig sits at the western end of the Schlei fjord, shaped by Vikings, Danish kings, and centuries of border conflicts. The town holds a UNESCO World Heritage Site in its backyard, a 1,700-year-old boat in a converted drill hall, and one of the best-preserved medieval monastic complexes in northern Germany.

-
Schleswig Cathedral
The cathedral's 112-metre neo-Gothic tower was funded by Franco-Prussian War reparations and completed in 1894, capping a building that began as a Romanesque basilica in 1134. Inside, the carved Bordesholm Altar stands as one of the most significant works of late-medieval sculpture in the region.
-
Gottorf Castle
The largest castle complex in Schleswig-Holstein sits on its own island in the Schlei, and under Duke Friedrich III in the 17th century it became a centre for science and Baroque garden design that produced the pioneering Gottorf Globe planetarium. Today the wings house two major state museums spanning archaeology and contemporary art.
-
Viking Museum Haithabu
Haithabu was one of the most important trading hubs in Viking-Age Europe before it was destroyed in 1066, and the site was declared a UNESCO World Heritage property in 2018. The museum, open since 1985, holds the oldest preserved ringing bell in Northern Europe alongside reconstructed houses built with historically verified materials.
-
Danevirke Fortifications
Stretching 30 kilometres across the Jutland Peninsula, this earthwork system began around AD 650 and was expanded by King Gudfred in 808 and King Harald Bluetooth in the 10th century, making it the largest archaeological earthwork in Northern Europe. The 12th-century Waldemarsmauer brick wall is the most visible surviving section.
-
Nydam Hall (Nydam Boat)
A 4th-century oak rowing vessel discovered in a Danish bog in 1863 now sits inside a former Prussian military drill house on the Gottorf museum island. At nearly 23 metres long, the Nydam Boat is one of the oldest surviving plank-built ships in the world and predates the Viking Age by several centuries.
-
Fisher Settlement Holm
After the Thirty Years' War and a severe plague, the fishermen of Holm founded a mutual aid society called the Holmer Beliebung in 1650, and it still exists today. The settlement dates to around the year 1000 and its fishermen held exclusive rights to the Schlei confirmed by Danish King Christian I in 1480 and reaffirmed as recently as 1924.
-
St. John's Monastery
Founded between 1194 and 1200 as a Benedictine nunnery, this is considered the best-preserved medieval monastic complex in Schleswig-Holstein, and it has been in continuous use ever since. The Bellmann organ inside is linked to the melody of the Schleswig-Holstein regional anthem.
