The lower decumanus, commonly called Spaccanapoli, is a road artery of the historical center of Naples and is one of the most important streets of the city. It is along the decumanus and Decumano higher (decumani Naples), one of the three main streets of the urban plan designed in the Greek era and crossing throughout their length the ancient Neapolis. Considering the origin, it would then be more appropriate to speak of plateia and not "decumanus", naming the Roman era which by convention has replaced the original. The lower decumanus became between the Middle Ages and the nineteenth century important both for the convents of religious orders for both homes of powerful people who lived there. The street is also commonly called "Spaccanapoli" as sharply divided, with its perfect linearity, the ancient city between the north and the south. Originally the track was built from Piazza San Domenico Maggiore and went on to Via Duomo. In Roman era, the road is also stretched and incorporated the current Piazza del Ges� Nuovo area as the remains of Roman baths discovered in the cloister of Santa Chiara Basilica. During the Renaissance the way underwent tremendous changes, the Gothic structures were recasted or buildings were realized on soils of old demolished buildings. The main architects of the Neapolitan Renaissance were Giovanni Francesco Mormando and Giovanni Francesco di Palma who designed the Marigliano Palace and the Palace Pinelli. During the sixteenth century, the Viceroy Don Pedro de Toledo began a process of territorial expansion towards the hill of San Martino and lined the decumano with an artery of the Spanish Quarter, in order to relate to the city center to facilitate the moving. Between the seventeenth and eighteenth centuries private and religious buildings underwent further alterations. In the nineteenth century some buildings were again restored to their original forms because of their importance and, in the last century, because of World War II, the church of Santa Chiara resumed his Gothic structure concealed by eighteenth-century stucco work. Decumanus is divided into three sections: The section started from Piazza del Ges� Nuovo to continue for now Via Benedetto Croce, going through Piazza San Domenico Maggiore, the square Nile and wide body of Naples; The central part is via San Biagio dei Librai; Instead, via Giudecca Vecchia, a part of Forcella, passing the intersection with Via Duomo, is the final stretch of the decumanus. The modern conception of "Spaccanapoli" also includes the expansions that happened during the sixteenth century, which have seen lengthen the initial stretch to the Spanish Quarter. Meaning the Spaccanapoli name, the decumano starts then from Via Pasquale Scura, located on top of the Spanish Quarter. Soon after you get to the central part, which begins with the intersection of Via Toledo, and is formed by the streets Maddaloni, Domenico Capitelli, Benedetto Croce and San Biagio dei Librai. The side of Forcella instead represents the final stretch. Along Via San Biagio dei Librai, one of the hinges (or stenopos) which rises to the north, connecting the lower decumano to the higher one, it's Via San Gregorio Armeno.
