Since the fall of Communism in 1989, several Communist-era buildings have been refurbished, modernised, and used for other purposes. Perhaps the best example of this is the conversion of obsolete retail complexes into shopping malls and commercial centres. These giant, circular halls, which were unofficially called hunger circuses due to the food shortages experienced in the 1980s, were constructed during the Ceaușescu era to act as produce markets and refectories, although most were left unfinished at the time of the revolution.
