The Vatican has released the first photo of Pope Francis since his hospitalization. The photo shows Francis at the chapel in Rome’s Gemelli hospital. He is seen wearing a stole, a vestment worn to concelebrate Mass.

The release of the photo a month into his treatment came after dozens of young people gathered under the pontiff’s windows to offer wishes for a quick recovery.

Pope Francis is registering new slight improvements in his monthlong treatment for pneumonia in both his lungs, the Vatican said Monday, as it also provided some details on the first photo of the pope released since his hospitalization.
