The longest street in the quarter of the castle. You must walk along it to admire the façades of most of its Baroque houses. All these beautiful homes which appear one after another grant the street a certain residential look. Everything transmits calm and comfort. At No. 9, a labyrinth of galleries and caves. A low passageway underneath, sometimes ribbed where the water flows, from the rooms, a pale light, strange background music, statues, a fountain where wine flows, in a word: mystery.
