Tatlin's Tower was a design conceived by Russian architect Vladimir Tatlin, which was supposed to be constructed in St. Petersburg (then Petrograd) after the the Bolshevik Revolution of 1917, as Russia's answer to the Eiffel Tower and the Statue of Liberty. The plan never came to fruition, however, and the tower was never built. Now PHL Architects have taken that design and revised it for the 21st century, proposing a version in Jakarta that would house people, as well as livestock farming; fish and insects farming; public spaces; energy production; water and air treatments; and purifier plants. Like the original, it's a lot of fun to look at even if it's never going to be built.
