The phrase 'picturesque street' might have been invented to describe this tiny cobbled lane with its miniature workers' cottages. After a lengthy reconstruction, the Lane has reopened and now features displays on how past residents of the street used to live. A few of the souvenir shops do remain. It was on this street, or so legend has it, that 16th-century alchemists laboured to discover the Philosopher's Stone to make gold from lead. Franz Kafka spent evenings at his sister's house, N°22.
