The Northern German Defence Line 1916-18 (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 German flank.
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 is later known as the
First Danish-Prussian war 1848-1851. It
ended without a lasting peace and both politivcal and military
it was a stale mate. The peace treaty was dictated by the big powers, England, France and Russia.

The Defence Line was forgotten by most people a covered by natural

storages for potatoes.
But the Danes that had seen the batteries, the boys
who played around them remembered what they looked like and what was in them.
In the mid 1970’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 constructions. Most
