The Kremlin walls are powerful defensive structures surrounding the Moscow Kremlin. They were built in the late 15th – early 16th centuries and are a striking example of Russian defensive architecture. The walls are approximately 2235 meters long and range in height from 5 to 19 meters, with a thickness of up to 3.5 meters at the base.
The Kremlin walls are made of red brick and adorned with crenellations, giving them a distinctive appearance. Along the walls are 20 towers, each with its own unique architectural features. The most famous of these are the Spasskaya, Nikolskaya, and Senatskaya towers.
The Kremlin walls served not only as protection for the Kremlin but also fulfilled a symbolic function, representing the power and independence of the state. Today, they are an important historical and cultural landmark of Moscow, attracting numerous tourists and being a part of Russia's historical heritage.
