Sicherungsstellung Nord (Defence Line North) was build by the Imperial
German Army in the years 1916-1918, to prevent an
invasion by either landed
English troops, or an attack by Denmark
900 concrete and timber rooms and artillery platforms were build across the Southern
Jutland. From the Lillebaelt in the east to
the Island of Roemoe in the west
this very strong and heavily defence line blocked the Northern flank.
How could it be possible for Germany to build a Defence Line in an area that
is known to be Danish?
In 1848 a rebellion started in two of the three the small Danish duchies
Slesvig and Holsten. It was supported by Prussia.
The Danish Army moved into the region, and won what later is known as the
First Danish-Prussian war
It ended without a lasting peace, but a treaty dictated by the big powers,
England, France and Russia.
Denmark it was considered a great victory.

1864 Prussia provoked the Danish King, and he acted as Germany hoped, and
the second Danish
War was a reality.

Denmark had a series of defeats, the last at Dybbøl outside the town
3 month the Danish palisades were bombarded by better German artillery than
the Danish. The Danish positions were
occupied, and only a peace
treaty saved the remaining troops at the little island of Als.
This peace meant, that Denmark lost the southern part of Jutland, 20 % of the
territory, and overnight the Danish population in
the area became German
subjects. The Area was considered German, the names of the cities were changed and
the Danish flag
German became the language in the schools.
Also the young men were enlisted in the German Army.
1864 all the green areas became
German and the new boarder was drawn
at the top of the light-green area.
After 1920 the boarder was moved south
to the midle of the light green area.
At the time the defence line was build, the area was Germany and the
After World War 1, a referendum was held in the area. The people in the
three former Danish duchies were able to

looked like and what was in them.
In the mid 70’s a Danish engineer, Mogens Scott Hansen, got interest in the
defence line. He quitted his job, and used 15 years to
listen to witnesses, draw and
photograph the constructions and trace the forgotten and concealed
