Hi Leanora, BobG & Robert,
Leanora, I have sent you an instant message with my information ok!
BobG, when looking at the watercolors I believe they are in sequence i.e. Nicholas I study, schoolroom, children's bedchamber, Empress bedroom, then it is The Raspberry Drawing Room with a caption that says "On the other side of the semicircular central bay ..." This room was the chapel c1900. Therefore if I am correct in my deduction, Nicholas I's suite would have been in the left wing where Nicholas II lived. The schoolroom and bedchamber of the grand dukes are high ceilinged with window embrasures that would have been on the main/first floor. I have to look again at all my notes to decipher what rooms were prior to N&A's years! I too am curious of the rooms of the right wing especially of the second floor.
I was looking at some old downloads from the site and I found a page on the English Suite. It states that these were Nicholas I's private suite and actually has a copy of the watercolor of GD Mikhail and Konstantin's bedroom(from the Tsarskoye book). So I think the sequence going up the Right Wing (on the courtyard) might be Study of Nicholas I, Schoolroom, GD Mikhail and Konstantin's bedroom. I think the reference on the other side of the the semi circular bay is just a reference to the State Drawing room earlier in the book.
Still would love to have more details on the Right Wing, if anyone can help?
