Recently, on World Architecture Day, various English cathedrals had an absurd but highly entertaining argument on Twitter over which cathedral is the most beautiful of them all. (They kept it very civilised – they’re good Christians, after all.) They had a point too: cathedrals around the world can boast some of the most astonishing architectural feats in history. Their intricate, ornamental style unsurprisingly attracts many photographers to the subject. We’ve selected some of the best pictures in our library of cathedrals from Britain and beyond – but we won’t judge, you can decide for yourself which one is your favourite.
