The object was initially intended as a marine news school and was later named "coral". Construction began in 1939 in a heavily forested area two kilometers northwest of Lobetal, north of Bernau. The site originally belonged to the Hope Valley institutions.
Due to the increasing danger from aerial bombs, it was decided to move the command center of the High Command of the Navy (OKM) from Berlin to a safer area. On January 30, 1943, it moved to the Koralle camp. A little later the main radio station of the commander of the submarines (BdU) was set up on site. With this, all communications for the submarine war entered the station's bombproof news bunker.
After the advance of the Red Army and encirclement of Berlin, the order to move to the alternative quarters of the Trout property near Plön was given on April 19, 1945, and eight days later to Flensburg-Mürwik.
After the war ended, much of the facility was blown up by Soviet troops. The ruins are still in place.
The underground bunker and the residential building of Grand Admiral Dönitz have been preserved to this day.
There was an anti-aircraft bunker, a high bunker and an underground bunker. The OKM headquarters operated in the underground bunker. There was also an officers' casino, barracks, several fire water ponds and other smaller objects. Some of the buildings were connected underground. The Koralle warehouse was equipped with numerous telecommunications equipment.
