The State Hermitage The Winter Palace is one of the most splendid buildings in St. Petersburg. Almost all the Romanovs starting from Catherine the Great resided there. The palace had hundreds of rooms; many of them were State Halls the interiors of which are preserved till the present days and open to visitors.
The Hermitage Museum, St. Petersburg, Russia - Only had 1 day to explore this incredible museum, unfortunately, but definitely hope to go back. There is so much incredible art here - they say, if you spend 1 minute in front of each piece in the Hermitage you would spend over 7 years in the museum! :-)
