As far as I can see, the walls of the Alexandrovsky Hall is decorated with the various quarterings or arms that make up the great arms of the Russian Empire, thus including the arms of such (nowadays) independent countries like Finland, Poland, Estonia, Latvia, Lithuania, Norway, Georgia etc. and foreign regions like Schleswig, Holstein, Oldenburg, Kiev, Vitebsk etc.
The Andreyevskiy Hall (the throne hall) is decorated with the arms of all? guberniyas? of the Russian Empire, in addition to the middle imperial arms on the canopy wall behind the dais with the thrones.. On the wall close to the throne I've spotted the arms of the Volynskaya Guberniya (a silver cross on red), which today is in Ukraina, so I guess it's the former imperial guberniyas, not the current Russian oblasts. But does it include the guberniyas in Poland, Finland etc.?
Can anybody confirm this or even better: Have a list or plan of which arms are displayed where?
