The basilica will be kept open until at least midnight on Thursday to allow the faithful to mourn. Francis' funeral will be held Saturday at 10 a.m. (2 a.m. ET) in St. Peter’s Square, after which the Vatican press office is expected to release details of the conclave that will elect the next pontiff.

In the streets around the Vatican, where Pope Francis used to make impromptu outings, some of the shopkeepers are mourning the man they knew, not as the leader of a church or head of state, but as an ordinary person.

Pope Francis is breaking with tradition when it comes to where he will be laid to rest – choosing a light-filled basilica with an intriguing history instead of the grottoes of the Vatican.
