The semicircular rampart at the Dannewerk, near Bustrup, 1864. 'The Dannewerk as it now stands consists essentially of three distinct and separate earth-walls, which, small as they may appear in the accompanying map, are, nevertheless, works of tremendous extent, and defences which the best engineers admit to be almost impregnable. To the east stretches the "Oster-wolden," as it is termed, and which, literally translated, means the eastern rampart; while towards the west side of the coast extends the "Krum-wolden" (crooked rampart), together with the slanting Dannewerk proper, the greater part of which goes by the name of Valdemar's Wall...as it existed previous to the present improvements. These ramparts consist essentially of enormous earth-mounds or dykes, arranged like the mouth of a funnel, so as to drive any invading army up into the narrowest possible channel, at which point the "Bruckenkopf" or, tete-du-pont, is situated, where, from the great strength of the batteries, it would be almost impossible for any body of troops to force a passage'. From "Illustrated London News", 1864.
