Arch of Gratian, Valentinian and Theodosius

Ponte Sant'Angelo, originally the Aelian Bridge or Pons Aelius, is a Roman bridge in Rome, Italy, completed in 134 AD by Roman Emperor Hadrian (Publius Aelius Hadrianus), to span the Tiber from the city centre to his newly constructed mausoleum, now the towering Castel Sant'Angelo. The bridge is faced with travertine marble and spans the Tiber with five arches, three of which are Roman; it was approached by means of a ramp from the river. The bridge is now solely pedestrian and provides a scenic view of Castel Sant'Angelo. It links the rioni of Ponte (which was named after the bridge itself), and Borgo, to which the bridge administratively belongs.

The Porta Aurelia-Sancti Petri was one of the gates of the Aurelian walls in Rome (Italy). It was originally called the Porta Cornelia. The Porta Cornelia was immediately west of the bridgehead of the Pons Aelius, the current Ponte Sant'Angelo. This is where the Via Cornelia began, from which the gate took its name. In the first centuries AD this was not an important road, but that changed with the rise of Christianity. Constantine the Great had Old St. Peter's Basilica built in the 4th century, over the Roman and Christian necropolis on Via Cornelia. Between 270 and 280 the great Aurelian Walls were built around Rome. The Vatican Hill was only sparsely populated and remained outside the wall. The Basilica and this northern entrance to Rome, however, had to be able to be defended, and between 401 and 403 the Emperor Honorius had the Mausoleum of Hadrian converted into the Castel Sant'Angelo. The Porta Cornelia was built into the defensive walls of the Castle and gave access to the Vatican from the city. The gate was demolished after the Middle Ages. It is no longer known what exactly it looked like. The gate was also known as Porta Aurelia Sancti-Petri because the important Via Aurelia could also be reached by this gate and Via Cornelia. However, there was already a Porta Aurelia on the Janiculum (today's Porta San Pancrazio} and the addition of Sancti Petri ("at St. Peter's") is therefore intended to distinguish between the two gates.

Santi Celso e Giuliano is a minor basilica and papal chapel of the Diocese of Rome in the care of the Institute of Christ the King Sovereign Priest. It has held its basilica status by custom and practice since ancient times. The church is located on Vicolo del Curato number 12, just off Via del Banco di Santo Spirito, the road leading to Ponte Sant'Angelo.

The Tor di Nona is a neighborhood in Rome's rione Ponte. It lies in the heart of the city's historic center, between the Via dei Coronari and the Tiber River. Its name commemorates the Torre dell'Annona, a mediaeval tower which once stood there and was later converted into one of the city's most important theatres, the Teatro Tordinona, later called the Teatro Apollo.

The Mausoleum of Hadrian, usually known as Castel Sant'Angelo (Italian pronunciation: [kaˈstɛl sanˈtandʒelo]; English: Castle of the Holy Angel), is a towering cylindrical building in Parco Adriano, Rome, Italy. It was initially commissioned by the Roman Emperor Hadrian as a mausoleum for himself and his family. The building was later used by the popes as a fortress and castle, and is now a museum. The structure was once the tallest building in Rome.

Campo Marzio (Italian pronunciation: [ˈkampo ˈmartsjo]) is the 4th rione of Rome, identified by the initials R. IV. It belongs to the Municipio I and covers a smaller section of the area of the ancient Campus Martius. The logo of this rione is a silver crescent on a blue background.

Parco Adriano is a park in Rome, Italy on the northern bank of the Tiber, just to the east of the Vatican. It contains the Castel Sant'Angelo.

The Monument to Terenzio Mamiani della Rovere is a memorial statue to an 18th-century patriot and statesman, located alongside the Corso Vittorio Emanuele II at a small piazza along Via degli Acciaioli. Mamiani (1799–1885) was in life a liberal Catholic, and posthumously acknowledged as having been a free-mason: his service as both minister in the Papal States and under the Kingdom of Sardinia, later Senator in the Kingdom of Italy bridged contentious or warring factions. The City Council of Rome approved the construction of the statue, at a cost of 10,000 lire, on 25 May 1885, four days after his death. In 1889, it was decided to place the statue in the Piazza Sforza Cesarini, some four blocks southeast of the present position, alongside the Corso. The design of a monument by Mauro Benini was chosen by a committee led by the sculptor and council-member Ettore Ferrari. The ultimate cost was over 20,000 lire and paid out in various installments: 3000 lire paid for the initial design paid to Benini 4000 lire paid for a clay-plaster model 5000 lire paid for completion of the statue 7000 lire paid for the completion of the monument in situ 1000 lire for complete assemblyThe statue was inaugurated on 2 March 1893, in a ceremony attended by Terenzio's widow, Angela Mamiani della Rovere. During his life, Terenzio had published a work examining and praising of Nicola Spedalieri's opus Il Diritti dell'Uomo. Thus perhaps it is ironic that by 1927, another council in Rome decided to move Spedalieri's statue and monument from a busy street-piazza lot between the Palazzo Vidoni and Sant'Andrea della Valle, and place it in Piazza Sforza Cesarini, dislocating Terenzio to his present spot along Via degli Acciaioli. The statue in Carrara marble depicts the elder gaunt Terenzio, seated but alert and leaning forward, with a quill pen in his right hand, and a book in his left hand.

Ponte Vittorio Emanuele II is a bridge in Rome constructed to designs of 1886 by the architect Ennio De Rossi. Construction was delayed, and it was not inaugurated until 1911. The bridge across the Tiber connects the historic centre of Rome (Corso Vittorio Emanuele, whose axis the bridge extends, and piazza Paoli at the bridgehead) with the rione Borgo and the Vatican City, close what is left of the ancient Pons Neronianus. The bridge commemorating Vittorio Emanuele II of Italy is carried in three arches spanning a distance of 108 metres. It is decorated at the ends with high socles carrying colossal bronze winged Victories and over each of the piers with massive allegorical travertine sculptural groups.

The Bust of Antonio Cepparelli is a sculptural portrait bust by the Italian artist Gian Lorenzo Bernini. It was executed around 1622. It is in the museum of the church of San Giovanni dei Fiorentini in Rome.

The Basilica of San Giovanni dei Fiorentini ("Saint John of the Florentines") is a minor basilica and a titular church in the Ponte rione of Rome, Italy. Dedicated to St. John the Baptist, the protector of Florence, the new church for the Florentine community in Rome was started in the 16th century and completed in the early 18th, and is the national church of Florence in Rome. It was lavishly decorated with art over the 16th and 17th centuries, with most commissions going to Florentine artists.

The Pons Neronianus or Bridge of Nero was an ancient bridge in Rome built during the reign of the emperors Caligula or Nero to connect the western part of the Campus Martius with the Ager Vaticanus ("Vatican Fields"), where the Imperial Family owned land along the Via Cornelia.
