Other than moving its capital to St. Petersburg and then back to Moscow, has Russia ever considered moving its capital elsewhere (excluding in times of war-related emergencies--such as during WWII, when Stalin considered moving the Russian capital to Kuybyshev (now Samara) if Moscow would have fallen to the Nazis)? If so, to where?

I seem to recall that there was some speculation that Russia could move its capital to Constantinople in the event of a Russian conquest of that city, but I'm not sure if such a move was ever actually considered by the Russian government itself.

Any thoughts on my question here?
