The work of Slovak architects Štefan Svetko, Štefan Ďurkovič and Barnabáš Kissling, in the form of an upturned pyramid, got on the list thanks to its unusual design.
Other absurd buildings include, as the SITA newswire quoted the Business Insider, monuments on the Croatian hill of Podgarić, on the mount Buzludzha in Bulgaria, on the Mrakovica hill in Bosnia-Herzegovina, as well as the Makedonium in Macedonian Krushevo and the Monument of Founders of the Bulgarian State in the town of Shumen.

Other gems from the list are the headquarters of the Bank of Georgia in Tiflis, the Forum Hotel in Polish Krakow, the circus in Chishinau, Moldova; Druzhba rehab facility in Yalta, Ukraine, the Russian State Scientific Center for Robotics and Technical Cybernetics in St. Petersburg, and the Salut Hotel in Kiev, Ukraine.
