The Fortifications of Copenhagen
 

At the time, one of the greatest fortifications in Europe. 
It's also one of the best preserved - maybe in the world. 

 

 
 


The old fortifications around Copenhagen dating from the 17th century were demolished during the the years from 1872, and the constructions of a new defence system was commenced in 1885.
The old naval and coastal forts were modernized, and a number of new forts north of the capital were constructed together with  a new defence line "Vestvolden" (The Western Enceinte) about 12 km south west of Copenhagen. The shore defences also received some new naval and coastal forts and batteries. 

At the time of its construction the defence line was a worthy opponent for any aggressor with new and modern 15 cm artillery, mitrailleuses and machine guns which were hidden behind concrete walls.
But military developments went very fast at the time, and just 20 years after its construction, the defen-ce line was out of date from a technological point of view. Also it was too close to the capitol. The fortifi-cations needed a lot of manpower to be effective. All the 50.000 men that were enlisted to protect Danish neutrality in 1914, were deployed around Copenhagen.

As a result of this knowledge, a political agreement from 1909 became the basis for a new defence line 30 km west of the city - the Tune stronghold between the Køge Bugt (Koge Bay) and Roskilde Fjord (the Fjord of Roskilde). This line is the narrowest point on the island of Sjælland.  The construction work started just after the outbreak of World War I.

In 1920 the defence lInes of Copenhagen were abandoned.
