Secret Prague ('Secret' guides)

A totally overlooked Art Nouveau masterpiece, a forgotten Cubist lamp-post, secrets of the castle alchemists, the message in the hidden palindrome on Charles Bridge, the Kabbalistic mysteries of the Jewish ghetto, a thief's shrivelled forearm hanging in a church, a statue revealing its intestines, the largest wind tunnel in the Czech Republic, a fragment of the Great Pyramid of Cheops in a pet cemetery, a clock that runs backwards, a house/museum painted blue to meet the needs of the partially blind musician owner …

Unmissable for lovers of architecture, from Baroque to Art Nouveau via Cubism, and the European capital of alchemy and esotericism in the 17th century, Prague offers a myriad of little-known marvels.
