Genex Tower (or Western City Gate) is one of the most famous examples of Yugoslavian brutalism architecture. The sky scraper was built in 1979 by architect Mihajlo Mitrović. The left part of the building contained apartments and the right part was suited for offices. In communist era there was the office of “Generalexport” here but today the right side is used as a stand for advertisements.
On the top there was a rotating restaurant here but today it is closed as I know.
Even being in a very bad condition the building still inspires, and you have a lot of controversial feelings when you stay nearby.
One may say that the building dominates and suppresses surroundings but it is a common for almost all modernist architecture.
For me modernist architecture of 70s looks like something from pages of novels of the Science Fiction Golden Age. I agree that it may look suppressing but for me there is something cosmic in it, something breath-taking. It is like the artifact from the era when people were still dreaming about stars :)
