What's inside the Moscow Kremlin?

The highest building of the city and Muscovite Russia was the Ivan the Great Bell Tower, built in 1505–08 and augmented to its present height in 1600. The Kremlin walls as they now appear were built between 1485 and 1495.[8] Spasskie gates of the wall still bear a dedication in Latin praising Petrus Antonius Solarius for the design.
