6. Palace of Winter

After accounting for inflation, it is estimated that the construction of Saint Petersburg, Russia’s Winter Palace, cost much more than $6 billion. From 1732 to 1917, the Russian Emperor resided in this mansion for almost two centuries. The final occupants of the Winter Palace were Nicholas II and his unfortunate Romanov family.

Since the tragic end of the Romanovs, no one has resided there. The Hermitage Museum of Russia is currently housed in the palace. The palace’s enormity never fails to astound those who come. There are 117 staircases and 1,500 rooms in it. Formal conference spaces, waiting areas, and private suites are among the available rooms.
