The room in Panteleimonos were guests are welcomed. This is in 1918 during WW1.
This photo was taken during WW2 in 1942 . You see a portrait of Hitler in the gallery under the large painting in the middle probably of the last Tsar Nicolas II.
This is a later image of that room found on a Russian website. It is a very intriguing room with all those portraits. On the place were Hitler used to hang in the war it seems that a women has taken his place. Thanks to our friend Keliotes we know that the woman is Queen Frederica (1917 – 1981) and beside her king Paul (1901 – 1964). From the reactions on this post we learn that this room is destroyed by fire in 1968. Thanks for your comments.
