The facility was initially intended as a naval communications school and was only given the name "Koralle" later. Due to the ever-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 in the middle of the forest. Construction began in 1939. On January 30, 1943, it moved into its headquarters in the Koralle camp. A little later, the main radio station of the Commander of the Submarines (BdU) was also set up on site. This meant that all communications for the submarine war now came into the station's bomb-proof communications bunker. At times, all German naval operations of the Second World War were coordinated here. The bunker was then blown up by the Soviets. Today, the bunker can be visited and many climbers practice on it.

Unfortunately, the castle no longer exists. A small model is on the site. The castle park has been partially restored.

Old city wall of Bernau.

Mighty city wall, very nicely preserved in parts. Can be driven very well on the laid narrow slab path within the city wall. Imposing gates and wall towers e.g. Lughaus.

A very nice pond in front of the former mill and the castle.

@Frank from Hönow is probably right. I found the following article about this: https://www.maz-online.de/Lokales/Oberhavel/Muehlenbecker-Land/Schloss-Dammsmuehle-Viel-Zusracht-fuer-Restaurant-und-Hotelprojekt. Since I like to do a lost place tour, I'm a little bit divided. But all that stops the decay is ok

The Dammsmühle Castle, which is picturesquely reflected in the lake, is currently scaffolded and is being renovated. But that can drag on for a few more years.

The castle no longer exists, but most of the outbuildings and the castle church have been beautifully restored. The palace park is in progress. The tourist information office is also located on the premises.
