Caravaggio's Adoration of the Shepherds (1609, shown above) is going to be restored, starting next week, and the public is invited to watch the restoration process. According to The History Blog, small groups of tourists and students will be invited to watch the restorers work. Apparently, there isn't too much restoration work which needs to be completed; the project is scheduled to end in February.
Swoon! I would love to be there. I heart Caravaggio SO MUCH.
