Photograph of the sitting room of Grand Duke Friedrich Wilhelm of Mecklenburg-Strelitz at Schloss Neustrelitz. There is a table covered by a cloth and piles of books. Around it are chairs decorated with the family crest. Three portraits hang on the wall above and there is a tall cupboard in the corner. Part of a marble bust can just be seen to the right.

Schloss Neustrelitz was the principal palace of the Grand Dukes of Mecklenburg-Strelitz. The palace was destroyed by fire in 1945. The Mecklenburg-Strelitz family had close ties to the British Royal family dating from the marriage of Princess Charlotte of Mecklenburg-Strelitz to King George III.
