Parco Adriano

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.

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 Arch of Gratian, Valentinian and Theodosius (Latin: Arcus Gratiani, Valentiniani et Theodosii) was a triumphal arch built between 379 and 383 AD in Rome. It was situated at the south end of the Pons Aelius, near to the site later occupied by the church of San Celso. It formed as a monumental entrance arch to the bridge. It was built by Gratian, Valentinian II and Theodosius I from their own money. It was mentioned in the Einsiedeln Itinerary, the Mirabilia and the Ordo Benedicti. It was destroyed before the 14th century and the papacy of Pope Urban V, an era when it was described as destroyed. Some remains were still visible until the 16th century.

Piazza Pia is a historic square located in the Borgo district of Rome, nestled between Castel Sant'Angelo and Via della Conciliazione. Named after Pope Pius IX, the square has long played a strategic urban role and has undergone numerous transformations over the centuries. As part of preparations for the Jubilee 2025, Piazza Pia was completely redeveloped, becoming the largest pedestrian-only urban space in the city.

Sampietrini (also sanpietrini) is the pavement found in the historic district of Rome and in St. Peter's Square, Vatican City. The earliest examples were made by trimming large blocks that had been used in ancient Roman roads, as recently discovered in fifteenth- and sixteenth-century archeological excavations. The first documented use in Rome of "sampietrini" stones was during the reign of Pope Pius V (1566–72). Over the next two centuries, the stones were used to pave all the main streets of Rome, because this mode was superior to brick, as it provided a smoother, stronger surface for carriages. Advantages of sampietrini: It creates small channels between the bricks that allow water to pass. It can be adapted to the irregularities of the underlying ground. It is a long-lasting material. Disadvantages of sampietrini: Over time, the underlying ground will become irregular. It is slippery when wet. Sampeitrini's peculiarities make it unsuitable to streets where traffic travels at high speed. Nowadays, its use is largely confined to historical or very narrow streets in the center of Rome (e.g., in Trastevere), where traffic is light and slow. The widespread availability of sampietrini made it a weapon of choice in Italian riots since the 1960s. In July 2005, the mayor of Rome, Walter Veltroni, declared that the sampietrini pavement was causing problems: its irregularity could be dangerous to moped riders and other two-wheeled vehicles; heavy vehicles passing over it created noise and vibrations damaging to adjacent buildings. While these concerns were countered with the argument that inadequate maintenance was at fault, Veltroni said that the sampietrini would be removed, reserving them solely for pedestrian streets.

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 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.

Auditorium della Conciliazione, also known as Auditorio Pio, is an audience hall and concert hall on the Via della Conciliazione in the Borgo district of Rome. Conceived in the 1930s as part of a vast Mussolini-ordered redevelopment of the district, it was not completed until 1950 after post-World War II work by architects Marcello Piacentini and Giorgio Calza Bini. Surrounding it are wings of the large Palazzo San Pio X, a broadcasting facility also part of the 1930s conception. Both buildings open onto the long perspective from St. Peter's Basilica to the Ponte Sant'Angelo created by the redevelopment. The venue's role as a pontifical audience hall began when it was inaugurated by Pope Pius XII. But in 1971 it was replaced in this role by the new Paolo VI Audience Hall. As a concert hall it served from 1958 to 2000 as the performing home of Rome's main symphony orchestra, the Orchestra dell' Accademia Nazionale di Santa Cecilia, and in February 2001 it hosted a unique week-long filmed residency by the Berlin Philharmonic and Claudio Abbado. When the Santa Cecilia orchestra too moved away, the building underwent a lengthy refurbishment before reopening on April 29, 2005, with the ceremony of the David de Donatello Awards presented by l'Accademia del Cinema Italiano.

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.

San Michele Arcangelo ai Corridori di Borgo was a church in Rome dedicated to St. Michael, the Archangel, important for historical and artistic reasons. The church, traditionally linked to the legend of the appearance of St. Michael above Castel Sant'Angelo and seat of the confraternity of the same name, was founded in the Middle Ages and rebuilt in 1564. The 16th century church, a small hall building, was the work of the Florentine mannerist architect Tiberio Calcagni, and had a side chapel on the left side of the first bay. The building was decorated with frescoes and paintings from the mannerist period, and housed a fresco from the 15th century, the Nursing Madonna, attributed to Antoniazzo Romano, accidentally found in 1825 in the courtyard wall. The church was demolished in 1939 to allow for the enlargement of two roads: Borgo Sant'Angelo and Via della Traspontina, as part of a project to open Via della Conciliazione. After its demolition in 1939 the most important works of art were transferred to the reconstructed oratory of the Nunziatina on the Lungotevere Vaticano.

The Embassy of the Republic of China (Taiwan) to the Holy See (Chinese: 中華民國駐教廷大使館) is the diplomatic mission of the Republic of China (as known as Taiwan) accredited to the Holy See, one of its few de jure embassies in the world, and the only one remaining in Europe. It also has responsibility for relations with the Sovereign Military Order of Malta.Its counterpart in the Republic of China is the Apostolic Nunciature to China in Taipei.It is separate from the Taipei Representative Office in Italy in Rome, which functions as a de facto embassy in Italy.

The Ospedale di San Carlo (lit. 'St. Charles's Hospital') was a building in Rome, important for historical and artistic reasons. Built at the end of the 18th century by the will of Pope Pius VI, the hospital was initially a branch of the nearby Santo Spirito Hospital. Later it was used as a military hospital for the army of the Papal States and, after the capture of Rome in 1870, became the first Italian military hospital in the new capital. It was demolished in 1939 for the construction of the Via della Conciliazione.
