The best things come to those who wait - and that's certainly the case for the Room of Constantine. Taking a decade to complete, it's the last and most important of the restored Raphael Rooms at the Vatican Museums. The hall, which was painted by Raphael Sanzio and his students in the 1500s, is dedicated to the 4th century Roman emperor Constantine whose embrace of Christianity helped spread the faith throughout the Roman Empire.
