STARKNESS

 I thought it was more recent, but apparently Belgrade's BRUTALIST ARCHITURE (sorry, 'ARCHITECTURE'; can't fix the spelling) dates as far back as 1948 (actually, I date that far back, too...) although the apartment buildings in the above photo date from the 1960s. They look pretty grim here facing a couryard that no one ever uses and plants have never seen, but the apartments were built to last and have withstood the test of time.
