saint peter's church, vatican, inside saint peter's
This picture is of high above the rear (enterence) of St. Peter's Basilica in the Vatican City.
The latin words seen on the wall are part of the phrase "Quodcumque ligaveris super terram, erit ligatum etin coelis: et quodcumque solveris super terram, erit solutum et in coelis" meaning "I will entrust to you the keys of the kingdom of heaven. Whatever you declare bound on earth shall be bound in heaven; and whatever you declare loosed on earth shall be loosed in heaven." from Matthew 16:19.
