Churches, left to right: Annunciation Cathedral, Cathedral of the Assumption, Archangel Michael Cathedral and the Ivan the Great Bell Tower. The tower in the foreground is called the Secret Tower because of the secret tunnels dug beneath it during its construction in 1485.
The former Senate building, now called the Council of Ministers. Notice the facade actually is canvas or some other material painted to show how the buiulding should appears once renovations are completed. Many buildings undergoing restoration around Moscow were covered in such a way, revealing how the final renovated building should look.
