Is the Russian tourist attraction, the Polygonal Palace in Moscow?

Hello, the Polygonal Palace is in Moscow. The Polygonal Palace (Грановитая? Палата) is located on the west side of the Church Square. It is the only existing building in the Kremlin other than the church that was built during the period of Ivan the Great (Ivan III). Strict proportions and cubic volumes make the Polygonal Palace appear graceful, simple and clear. The walls are made of bricks and are inlaid with white stones cut into tetrahedrons from the front (east) side - hence the name of the Polygonal Palace. The palace was built in 1491 by Marko Friazin on the orders of Grand Duke Ivan Vasilyevich of All Russia. The thrones of previous Russian emperors such as Peter the Great were set up here. It was a hall where celebrations were held and foreign envoys were received.
