Natasha (Nataashka), a manager of a river cruise (must be an awesome job), sent this picturesque multiview card of The Kremlin located in the capital city of Moscow. It is a historic fortified complex that includes four palaces, four cathedrals, and the Kremlin Wall with Kremlin towers. The President of the Russian Federation resides in the said complex. Btw, kremlin are Russian citadels.
Thanks, Natasha! Nice stamp used:
