Keep in mind, was a very brutal war. The Nazis destroyed the palace all they could. Doors, floors and all the wooden things they used for their heat. Remember, any photo of the palace in 1944 !!!!! Again, the fascists DESTROY ALL!
I have memories of Anatolia Kuchumova of the palace in January 1944. It describes all the rooms and what was around the palace. In Russian. If necessary, I will send to your mail.
