This year St Peter's keys will be taken out to who knows where. The idea is to take a photo of the image, or a set of keys in places you visit during the summer. This might be a church you visit, or could be a place of natural beauty. For inspiration you might want to look at some Picturing God images on the Arts and Faith Loyola site, or search for St Peter's Keys to see earlier posts.
Can you find out where this year's keys are in the Cathedral?
