The Monument to the Third International would have loomed 400 metres over St Petersburg (100 metres taller than the Eiffel Tower) had it been built after the Revolution of 1917. The building was intended as a monument, exhibition space and location for the Comintern offices, and included several blocks within its structure, a cube, pyramid and cyclinder, that would revolve at different speeds. Unfortunately for architect Vladimir Tatlin, the Civil War put paid to his plans, although it was estimated that even if the country had been peacable enough to allow its construction, the vast frame would have used up all the steel in the Soviet Union.
All unbuilt structures tend to evoke a “what if?” response and Tatlin’s Tower has been given virtual life through this impulse in Takehiko Nagakura’s 1999 film of the same name. Nagakura uses CGI to show how the building would look against the skyline of the real St Petersburg.
