Vladimir Tatlin's Tower, also known as the Tatlin Tower, was an ambitious architectural project designed by Russian artist and architect Vladimir Tatlin in 1919. Intended as a monument to the Third International, it was envisioned as a spiraling structure made of iron and glass, standing over 400 meters tall. The tower was meant to symbolize the revolutionary spirit of the time and serve as a functional space for political meetings and exhibitions. Although the tower was never built, it remains an iconic example of Constructivism, a movement that sought to merge art and architecture with social purpose. Tatlin's design featured a rotating structure that would house different functions, reflecting the dynamic nature of the new Soviet society.
