Cretto di Burri ( crack of Burri ) or Cretto di Gibellina ( crack of Gibellina ) , also known as " The Great Cretto " , is a landscape artwork undertaken by Alberto Burri in 1984 and left unfinished in 1989 ( due to lack of funds ) , based on the old city of Gibellina . The original city of Gibellina was completely destroyed in the 1968 Belice earthquake . Gibellina has since been rebuilt , about 20 km from the city 's original location . In 2015 , to mark what would have been Burri 's one hundredth birthday , the work was finally completed
