The world-famous "mouth of truth" is inside a tiny Cosmetine Church of Our Lady. It is a disc carved with the head of the sea god, and it is said that it is placed in his mouth and cannot be pulled out if he lies. But it is said that this is only a manhole cover from ancient Rome, and it is a magical legend that posterity gave it. 💡: The mouth of truth queues up to take pictures, and you can put some tips into the box according to your wishes (there is also a Chinese sign, written "fragrant money" laughing at me).
