Vladimir Tatlin achieved fame as the architect who designed the huge Monument to the Third International, also known as
Tatlin's Tower. Planned in 1920, the monument, was to be a tall tower in iron, glass and steel which would have dwarfed the Eiffel Tower (it was a third taller at 1,300 feet high). Inside the iron-and-steel structure of twin spirals, the design envisaged three building blocks, covered with glass windows, which would rotate at different speeds (the first one, a cube, once a year; the second one, a pyramid, once a month; the third one, a cylinder, once a day). High prices prevented Tatlin from executing the plan, and no building such as this was erected in his day.
