The Vatican says Pope Francis died just after 7:30 a.m. local time on Monday, a day after he surprised many by appearing outside the Vatican on Easter Sunday to greet well-wishers.

His death came almost a month after he returned there after being hospitalized for double pneumonia. The Vatican said Francis died after having a stroke. St. Francis is now lying in state in a simple wooden coffin inside St. Peter’s Basilica. He is dressed in red liturgical vestments and his hands are folded, holding a rosary.

Interest in paying respects to him is high. The Vatican kept the doors open all night due to higher-than-expected turnout from mourners across the globe, closing the basilica for just an hour Thursday morning for cleaning.

The basilica will be kept open until midnight on Thursday to allow the faithful to mourn. The public mourning period will end on Friday at 7 p.m. (1700 GMT) and the funeral will be held on Saturday at 10 a.m. (0800 GMT) in St. Peter’s Square.
