The tour of the Middle Ages in Naples starts from the city's Cathedral, tetter known as "San Gennaro" because its remains and its blood are kept there. Once the secrets hidden between the tombs and the Gothic inscriptions have been discovered, our journey passes through a small gem: San Giorgio Maggiore, where we can admire the early Christian apse. Next stop will be the Church of San Lorenzo Maggiore, the burial place of the Knights of the order of the Templars or the Knot. Crossing via San Gregorio Armeno, famous for shepherds and cribs, you will arrive at the magnificent Federico II University, commissioned by the Teutonic Swabian Emperor Federico II, the oldest secular and public university in the world. Our journey will come as a final stop in the splendid Piazza Mercato, a place of historical facts and popular legends, a place of revolutions and death sentences and we will have the opportunity to visit the oldest Gothic church in the city: S. Eligio.
