Owing to its beauty the Kremlin was considered to be one of the finest fortresses of its epoch. It impressed all foreigners that came to the capital. However, its secrets were carefully kept, and speaking of the walls of the Moscow “castle” Englishmen said that no foreigner was allowed to have a close look at the walls of the fortress.
Now there are 20 towers in the Moscow Kremlin; the Italian architects – Antonio Fryasin and Pietro Solari – were made responsible for the main work. At the end of the 15th century, the length of the Kremlin wall was more than 2 km.
The oldest Kremlin Tower Tainitskaya (Secret) was built in 1485. It faces the Moscow River and its name is connected with a secret underground passage to the river so that the citizens were not left without water in case of a siege.
