I want to know the answer to the following question:
Which room is named for visit of Tsar Nicolas I of Russia?
All the background I'm provided with is that "Some of the rooms are named and decorated for particular visitors, such as the 1844 Room, decorated in that year for the State visit of Tsar Nicholas I of Russia, and, on the other side of the Bow Room, the 1855 Room, in honour of the visit of Emperor Napoleon III of France.". Is that enough to answer the question?
