Tatlin’s Tower

sketch of Tatlin’s Tower

Tatlin’s Tower,or the project for the Monument to the Third International (1919–20)-by Vladimir Tatlin,
that was never built. 
In materials, shape and function, 
it was envisaged as a towering symbol of modernity.

Tatlin's idea on tower:

The tower's main form was a twin helix which spiraled up to 400 m in height,
The main framework would contain four large suspended geometric structures.
These structures would rotate at different rates of speed.
At the base of the structure was a cube which was designed as a venue for conferences,
and this would complete a rotation in the span of one year.
Above the cube would be a smaller pyramid housing executive activities and completing a rotation once a month.
Further up would be a cylinder, which was to house an information centre
and would complete a rotation once a day.
At the top, there would be a hemisphere for radio equipment.
There were also plans to install a gigantic open-air screen on the cylinder,
and a further projector which would be able to cast messages across the clouds on any overcast day
