Kremlin. Ministries House
Kremlin has the shortest street in the city, 500 meters around (I don't remember its name). A half of the street you can see this building, built in XIX century for administration departments. Moreover there were balls and dancing parties as well as celebration ceremonies. Nowadays the republic ministries are situated here.
