Tatlin's Tower, also known as the Monument to the Third International, was an ambitious architectural project designed by Russian artist Vladimir Tatlin in 1919. The structure was intended to symbolize the ideals of the Russian Revolution and serve as the headquarters for the Comintern. It was envisioned as a spiraling tower made of iron and glass, reaching a height of 400 meters. Although the tower was never built, its design is considered a pioneering example of modernist architecture. The project combined elements of Constructivism and Futurism, reflecting the revolutionary spirit of the time. Today, Tatlin's Tower remains an iconic symbol of avant-garde art and architecture.
