The Fortifications of Copenhagen
The Naval Forts and Coastal Batteries in The first Defence Line

Just as many political and military doubts there were about the ground defence line, everybody agreed in the necessity of a naval defence line. The experience from 1802 and 1807, where Copenhagen was forced to surrender from the seaside, made it clear that this was the weak point of the city and the country.
  The Coastal Defence:
An inner line of the three old forts and batteries:
The Naval Fort "Trekroner"
The Naval Battery  "Lynetten" and
The Coastal Battery "Strickers Battery", which was reconstructed.

Furthermore three new constructions were made:
The Coastal Battery
"Kalkbraenderi Battery" 
The Naval Fort”
The Naval Fort "Proevestenen"
