The Danevirke is about 30 kilometres (19 mi) long overall, with a height varying between 3.6 and 6 metres (12 and 20 ft).
During the Middle Ages, the structure was reinforced with palisades and masonry walls, and was used by Danish kings as a gathering point for Danish military excursions, including a series of crusader raids against the Slavs of the south Baltic.
In particular, the 12th-century King Valdemar the Great reinforced parts of the Danevirke with a brick wall, which enabled a continued military use of this strategically important structure.
The reinforced parts of the structure are consequently known in Danish as Valdemarsmuren (lit: Valdemar's wall).
