I last heard it is scheduled to be finished in October, but of course, it is Italy.  You can check on its progress in real-time via the camera belowhttps://www.skylinewebcams.com/en/webcam/italia/lazio/roma/fontana-di-trevi.html

lol,   when will something be finished in Italy.  The true answrer is when it is finished.  As with all projects in Italy the most favorable date for completion is always given.  Why?  Italians want to put their best foot forward and for them to understand when you don't meet a deadline - you look bad -- does not register with them.I was there just two days ago and it is exactly the same as it was Mid June when I went there last.Fendi, a multi billion dollar organization is paying for this restoration, the workers know this and so why should they finish ??  They might not have a job upon completion.  CIAO
