Palace square (aka Dvortsovaya square) is the best known square of the city, we can definitely call it the main square in St Pete. It is located between the Hermitage museum and a beatiful building of the General Staff. An Alexander Column is there, it is a great sight you should definitely see. This place is good just to walk around and take some pictures, there is completely no any entertainment except for probably the most expensive souvenirs in town. So treat this place like a beatiful landmark. But you definitely should find at least a couple of minutes to take a quick look onto the city’s main square. Nevskiy prospect is in a hundered meters via the General Staff arch, Admiralcy building and St. Isaac’s cathedral are also in a stonethrow from here.
