When the popes are outside Italy, there's always a different feel in the Vatican. Even the employees seem more at ease (with the lessened security threat).
Here we recognize the Apostolic Palace, completed in 1590, where the Pope lives. It all seems a little desolate without him. It seemed even more so during the Sede Vacante MMV. You can see the upper ten windows of the papal apartments? The window on the far left, without a shudder (shutter), is a hallway. The rest of the windows are all closed up as he's on the road. Pray for the apostolic voyage in the "Land Down Under" and the success of the 23rd World Youth Day!
