From Piazza Nettuno, slip into the Sala Borsa Library: once a basketball court, a bank, a public market, a botanical garden. Today it is a public library with thousands of books, magazines and videos. Stop to read a book among the students, take a break just to enjoy the atmosphere of this place full of peace and light or visit the archaeological excavations. Under the crystal floor in the center of the room you can admire the sedimentation of various civilizations reliving centuries and centuries of history. What is certain is that you can not miss this stage, even if you pay attention to the clock at the entrance because in this magical place time flies!
