This is the famous St. Basil's Cathedral at the end of Red Square. The Kremlin is to the right (not shown) and is surrounded by a long yellow wall. This cathedral was built in the 1100's! They're always renovating parts of it (it's really big)
...разве не при Иване Грозном в честь взятия Казани ? А что за желтая стена ? Ладно, пусть мифы живут =)
