Bored of baroque churches? Seen every gilded altarpiece you want to see? Come to the Basilica of St John of God. If Seville cathedral is the world's most voluminous church, this basilica is surely one of the most opulently decorated. Barely a square inch of the interior lacks embellishment, most of it rich and glittering.
Once you've taken in the head-spinning details, climb upstairs behind the altar to where the saint’s remains are set deep in a niche surrounded by gold, gold and more gold.
