Barcelona's Gothic Quarter is full of things that look as if they have been waiting here since the Middle Ages. Some have. Some have not. A modern plaque can tell a medieval magic story, a bridge from 1928 can pass for Gothic, a saint's legend can attach itself to a street, and an apparently ancient palace can have been physically moved across the city. This seven-stop walk does not try to ruin the atmosphere. It makes the atmosphere more interesting by asking one question at every stop: what can we actually document, what belongs to legend or later folklore, and what can you still verify with your own eyes?
