The boxy grey building behind the tree is the papal apartments. This is generally where the Pope lives, and was during the time of our visit (Benedict XVI). The papal suite is on the top floor and his bedroom is behind the window at top right. However, when Francis first toured the bedroom, he shouted "You could fit 300 people in here!" and decided to move in to a more modest guesthouse elsewhere. He does however still give Sunday addresses from the adjacent window, which is the papal study.
