The history of Via del Corso began in 220 BC when
Gaius Flaminius censor built a new road to link Rome with the
Adriatic Sea in the north. The starting point of the road was
Porta Fontinalis, a gate in the
Servian city walls near present-day Piazza Venezia. In its first miles
Via Flaminia cut through the plain between the
Tiber and the eastern hills in a straight line. The
Field of Mars, as it was called, was at the time used as a training ground and pasture. Numerous tombs must have lined the road similarly to the
Appian Way. The open area outside the city walls went through a process of urbanization during the late Republican and early imperial age. The city gradually spread towards north and monumental public buildings were built along the road. A set of dynastic monuments around the
Mausoleum of Augustus was the most important development in the formerly unpopulated northern section of the district. The ancient name of Via Lata (which means
Broad Way) denotes that the street was considered wide, especially in comparison to neighbouring lanes but at three places along its length, it became narrower due to triumphal arches. The first was the
Arcus Novus erected by
Diocletian in 303–304, then the
Arch of Claudius (AD 51–52) stood further ahead (the
Aqua Virgo aqueduct crossed the road on top of it) and the third was later known as the
Arco di Portogallo. The most important ancient monuments along Via Lata were
Aurelian's Temple of the Sun, the
Ara Pacis, the
Ustrinum Domus Augustae, the Ara Providentiae and the
Column of Marcus Aurelius. A densely populated residential quarter from the Hadrianic era was discovered on the right side of the road between Via delle Muratte and Via delle Convertite. With the building of the
Aurelian Walls (AD 271–75) the whole area was incorporated into the city of Rome, and a new city gate (Porta Flaminia) was erected at present-day
Piazza del Popolo where the road left the urban territory. From around the year 600 AD, the Corso accommodated a welfare centre linked to feeding the populace at
Santa Maria in Via Lata and granaries at its southern end. During the Middle Ages the Via Lata, the present day Corso, effectively denoted a boundary, to the city which mainly developed to the south and east of it. Also for this reason here was built in 1339 the hospital
San Giacomo degli Incurabili, later rebuilt in the today form. From the fifteenth century, the Via del Corso became a fashionable street for new or renovated churches and new palaces for the nobility. However, by the mid seventeenth century, the street remained a mixture of different scales and architectural styles, some unfashionable, a number of churches lacked facades and some buildings were a combination of structures from different periods or were simply incomplete. The lack of regularity and decorum of this principal street of the city meant that it became a main urban priority of
Pope Alexander VII. In pursuing the nobility to complete their properties, he met with limited success; some just did not have the funds, some were content to avoid the issue by continuing to reside on their country estates In the case of unfinished churches, he encouraged ecclesiastical colleagues to act as sponsors. Where he met with greater success was over imposing order on the street by empowering the
maestri di strade, the municipal body in charge of streets, to clear, align and regularize the street . This meant the properties could be acquired and demolished if necessary, projections from buildings could be removed and others added to so as to maintain a consistent line of street frontage. He even had the ancient triumphal arch, the Arco di Portogallo, demolished because the central gateway of this arch effectively reduced the street width to almost half. Alexander took a particular interest in regularizing the
Piazza Colonna, about halfway along the Corso. In 1659, his family, the
Chigi, bought the incomplete Palazzo Aldobrandini, bordering the piazza and the Corso, and rebuilt as
Palazzo Chigi. Around the same time, the leading painter of the time,
Pietro da Cortona, developed a design for a ‘fountain palace’ in the piazza, a palace with a large fountain at the base of the façade, but this precursor of the
Trevi Fountain was not built. The Corso was also tied to Alexander's intentions to impress significant dignitaries paying official visits to the city. The Porta del Popolo was reworked and the Piazza del Popolo cleared. The two
Baroque churches facing onto the Piazza marked perpectivised vistas along the
Via del Babuino to the left, the
Via di Ripetta to the right and at the centre, the straightened and regularized Via del Corso leading to the Piazza Venezia. This complex of three streets is known as
Tridente. ==See also==
