San Francesco a Ripa is a church in Rome, Italy. It is dedicated to Francis of Assisi who once stayed at the adjacent convent. The term Ripa refers to the nearby riverbank of the Tiber.

Porta Portese is an ancient city gate, located at the end of Via Portuense, where it meets Via Porta Portese, about a block from the banks of the Tiber in the southern edge of the Rione Trastevere of Rome, Italy.

The Pontifical Institute of Arab and Islamic Studies (PISAI) traces the origins of its foundation back to 1926 and the work of the Missionaries of Africa (White Fathers) in Tunisia in a training centre for missionaries preparing to work in Muslim countries. In 1931 this foundation took the name Institut de Belles Lettres Arabes (IBLA). In 1949 it was decided to separate the teaching section from the other activities undertaken at IBLA which were more linked to the specifically Tunisian cultural scene. So a study centre was opened at Manouba (near Tunis) which welcomed students of Arabic language and Islamic sciences. Later, in accordance with a Decree of the Sacred Congregation for Seminaries and Universities dated 19 March 1960, this training institute was raised to the Pontifical Institute for Oriental Studies. In 1964, the Institute was transferred to Rome and its name changed to the Pontifical Institute for Arabic Studies thus avoiding any confusion with the already existing Pontifical Oriental Institute. In 1967, at the wish of Pope Paul VI, the Institute was situated in part of the Palazzo di S. Apollinare. The sole teaching language, other than Arabic, was French. In 1972 an English-speaking section was added. Italian was also adopted later. Since 1966, the Institute has had the faculty to award the Licentiate in Arabic and Islamic Studies at the end of a two-year course of study and preceded by a preparatory year. In accordance with Decree No. 292/80/5 of 25 May 1980, the Congregation for Catholic Education granted the Institute the authority to award the Doctorate. The name currently held by the Institute is the Pontifical Institute for Arabic and Islamic Studies (PISAI). Its new Statutes were approved by the Congregation for Catholic Education in Decree No. 826/79 on 13 September 2008.

The Ospizio di San Michele a Ripa Grande (Hospice of St Michael) or Ospizio Apostolico di San Michele in Rome is represented today by a series of buildings in the south end of the Rione Trastevere, facing the Tiber River and extending from the bank of Ponte Sublicio for nearly 500 meters. It stands across the river from the Rione Ripa and the area known as the Porto di Ripetta, once in the Aventine neighborhood of Rome. The Porto di Ripa Grande was the river port that served those coming up from the Mediterranean port of Ostia. This area was once a main port of Rome. While large seafaring ships could not forge easily up the Tiber river to Rome; smaller boats frequently brought supplies from the coast to the city and offloaded at the Porta.

Ponte Sublicio, also known as Ponte Aventino or Ponte Marmoreo, is a bridge linking Piazza dell'Emporio to Piazza di Porta Portese in Rome (Italy), in the Rioni Ripa, Trastevere and Testaccio and in the Quartiere Portuense. The most ancient bridge in Rome crossed river Tiber just downstream of the Tiber Island, in correspondence with the former ford that, during the protohistoric age, was a required stop along the north-south way, at the feet of the Aventine Hill. Its building has been ascribed to King Ancus Marcius (642 - 617 BC) by Livy and Dionysius of Halicarnassus.

Santa Maria dell'Orto is a Roman Catholic church in the Rione of Trastevere in Rome (Italy). It is the national church of Japan in Rome.

The church of San Cosimato is a church located in the city of Rome, Italy. It was originally built in the 10th century in the Trastevere rione and now includes the hospital known as "Nuovo Regina Margherita." Originally, it was built as a Benedictine monastery dedicated to Saints Cosmas and Damian, from whom it derives its name, and it carried the added designation of in mica aurea (“in the golden sand”) due to the presence of fluvial sand of yellowish color. The monastery was transferred from the jurisdiction of the Benedictine Order to that of the nuns known as the Recluses of Saint Damian (Recluse di san Damiano). From 1233, the church served as a hostel. Pope Sixtus IV had the church and monastery rebuilt in 1475, and after 1870, the convent was converted into a hospital. The façade of the church looks upon a public square that is also called San Cosimato. The church has a small Romanesque bell tower. The presbytery contains a fresco called Madonna and Child between Saints Francis and Claire, by Antonio del Massaro.

Santi Quaranta Martiri e San Pasquale Baylon is a Roman Catholic church, built in a late-Baroque style, located on Via San Francesco a Ripa in the Rione Trastevere, Rome, Italy.

Porto di Ripa Grande was the river port of Rome, just downstream the former Pons Sublicius, where the wares, going up and down the Tiber towards the dock of Fiumicino, were handled. The building of the muraglioni (massive walls) has erased its existence and function, just keeping a trace in the toponymy (the stretch of Lungotevere, that flanks San Michele a Ripa Grande, is called Porto di Ripa Grande, while Via del Porto is the narrow street that links the Tiber to Santa Cecilia in Trastevere and Santa Maria dell'Orto) and in the two ramps giving access to the quay of the river.

The Pons Sublicius is the earliest known bridge of ancient Rome, spanning the Tiber River near the Forum Boarium ("cattle forum") downstream from the Tiber Island, near the foot of the Aventine Hill. According to tradition, its construction was ordered by Ancus Marcius around 642 BC, but this date is approximate because there is no ancient record of its construction. Marcius wished to connect the newly fortified Janiculum Hill on the Etruscan side to the rest of Rome, augmenting the ferry that was there. The bridge was part of public works projects that included building a port at Ostia, at the time the location of worked salt deposits.

The Aqua Augusta was a short aqueduct in Rome. Owing to severe drought, the Emperor Augustus built the Aqua Augusta in or around 33 BC in order to supplement the Aqua Marcia, and then later the Aqua Claudia when required. However, the aqueduct was poorly designed and most of it collapsed in 27 BC.

In Ancient Rome, the Aqua Alsietina (sometimes called Aqua Augusta) was the earlier of the two western Roman aqueducts, erected sometime around 2BC, during the reign of emperor Augustus. It was the only water supply for the Transtiberine region, on the right bank of the river Tiber. This aqueduct acquired water mainly from a lake just north of Rome called Lacus Alsietinus (a small lake in southern Etruria, currently known as Lago di Martignano) and some from Lacus Sabatinus (Lago di Bracciano). The length of this mainly subterranean aqueduct was 22,172 paces (about 32.8 km) and had arches supporting 358 paces (about 0.53 km). Its water supply had a diameter of 392 quinariae (about 9 m). This water was not suitable for drinking, however, and emperor Augustus used it to fill his naumachia in Trastevere. This water supply allowed him and the public to enjoy sham naval battles. The water surplus was used for the irrigation of Caesar's horti (gardens) and for the irrigation of fields. Such an abundant supply of water gives an idea how much water Rome had at its disposal. In his chief work, De aquaeductu (written in 97 CE), containing a history and description of the water-supply of Rome, Sextus Julius Frontinus ascribes only a meager volume to the Aqua Alsietina. This makes sense, if the naumachia was no longer in use in his time (second half of the first century CE). Some traces of this aqueduct were discovered in 1720. An inscribed stone slab was found in 1887 near the Via Claudia. It is the only written record of the Aqua Alsietina. The fountain of the Acqua Paola in Rome, built under Pope Paul V announces wrongly on its triumphal arch that "Paul V restored the ancient ducts of the Aqua Alsietina". Actually the engineers had rebuilt the old Aqua Traiana, which had run close to the Aqua Alsietina.
