Fontana dell'Acqua Paola

The Aqua Traiana (later rebuilt and named the Acqua Paola) was a 1st-century Roman aqueduct built by Emperor Trajan and inaugurated on 24 June 109 AD. It channelled water from sources around Lake Bracciano, 40 kilometers (25 mi) north-west of Rome, to Rome in ancient Roman times but had fallen into disuse by the 17th century. It fed a number of water mills on the Janiculum, including a sophisticated mill complex revealed by excavations in the 1990s under the present American Academy in Rome. Some of the Janiculum mills were famously put out of action by the Ostrogoths when they cut the aqueduct in 537 during the first siege of Rome. Belisarius restored the supply of grain by using mills floating in the Tiber. The complex of mills bears parallels with a similar complex at Barbegal in southern Gaul.

There are many busts of Italian patriots of the Risorgimento, and foreigners who fought with weapons or words for the unification of Italy, on the Janiculum in Rome.

Trastevere (Italian pronunciation: [trasˈteːvere]) is the 13th rione of Rome: it is identified by the initials R. XIII and it is located within Municipio I. Its name comes from Latin trans Tiberim, literally 'beyond the Tiber'. Its coat of arms depicts a golden head of a lion on a red background, the meaning of which is uncertain.

The so-called Tempietto (lit. 'small temple') is a small commemorative tomb (martyrium) designed by Donato Bramante, possibly built as early as 1502 in the courtyard of San Pietro in Montorio, in Rome, Italy. Commissioned by Ferdinand and Isabella of Spain, the Tempietto is considered a masterpiece of High Renaissance Italian architecture.After spending his first years in Milan, Bramante moved to Rome, where he was recognized by Cardinal Giuliano della Rovere, the soon-to-be Pope Julius II. In Rome, Bramante was able to study the ancient monuments firsthand. The temple of Vesta at Tivoli was one of the precedents behind the Tempietto. Other antique precedents Bramante was able to study in Rome include the circular temple of the banks of the Tiber, Temple of Hercules Victor, believed at the time to be a temple of Vesta. However, circular churches had already been employed by early Christians for martyriums, like Santa Costanza, also in Rome. Bramante would have been aware of these early Christian precedents, and as a result, the Tempietto is circular. The Tempietto is one of the most harmonious buildings of the Renaissance. The temple was constructed from bearing masonry. The circular temple supports a classical entablature, and was framed in the shadowy arch of the cloister. It is the earliest example of the Tuscan order in the Renaissance. The Tuscan is a form of the Doric order, well suited for strong male gods (such as Hercules) so Tuscan was well suited for St. Peter's. It is meant to mark the traditional exact spot of St. Peter's martyrdom, and is an important precursor to Bramante's rebuilding of St. Peter's. Given all the transformations of Renaissance and Baroque Rome that were to follow, it is hard now to sense the impact this building had at the beginning of the 16th century. It is almost a piece of sculpture, for it has little architectonic use. The building greatly reflected Brunelleschi's style. Perfectly proportioned, it is composed of slender Tuscan columns, a Doric entablature modeled after the ancient Theatre of Marcellus, and a dome. Bramante planned to surround the building with concentric rings of colonnades, the columns of which would have been radially aligned to those of the Tempietto, but this plan was never executed.

San Pietro in Montorio (Saint Peter on the Golden Mountain) is a church in Rome, Italy, which includes in its courtyard the Tempietto, a small commemorative martyrium (tomb) built by Donato Bramante.

Santa Maria dei Sette Dolori is a Baroque church in Rome built attached to a convent in the rione of Trastevere, located on Via Garibaldi, near the intersection with Via dei Panieri. Construction of the church was begun in 1643 with plans by Francesco Borromini, annexed to an Augustinian nunnery that was founded by Camilla-Virginia Savelli Farnese, Duchess of Latera. However, when the fortunes of the House of Farnese declined, so did the funding for the church, and by 1655 the work was stopped. The convent underwent a number of tribulations during the nineteenth century, however, it was not deconsecrated in 1873, as were many other monasteries. Since then, the nunnery has slowly ebbed and most of the convent is now the Hotel Donna Camilla Savelli. The Diocese presently lists the church as being in the care of the few remaining nuns of the order of Suore Oblate del Santo Bambino Gesù. The monastery also served as a place to hide Jews from the fascist authorities active in the Holocaust during World War II. The facade of the church remains in brick, deprived of decoration. It has concave front and some odd-shaped windows that underscore Borromini's Baroque idiosyncrasies. The interior still contains some of the marble sculptural decorations plus a St Augustine and the Mystery of the Trinity by Carlo Maratta and a canvas by Marco Benefial.

The Orto Botanico dell'Università di Roma "La Sapienza" (12 hectares), also known as the Orto Botanico di Roma, is a botanical garden operated by the Sapienza University of Rome and located at Largo Cristina di Svezia 24, Rome, Italy. It is open every day including Sundays; an admission fee is charged. The garden was established on this site in 1883, although it is the successor to the Papal Botanical Gardens going back to the Renaissance. It is sited on the slopes of the Janiculum overlooking the 17th-century Palazzo Corsini, which was from 1659-1689 the residence of Queen Christina of Sweden, now the headquarters of the Accademia dei Lincei. Part of the current Botanical Garden used to be the private garden of the Palazzo Corsini. After the Palace became property of the Italian state, they were merged with the existing Papal gardens to create the current lay-out.Today the garden contains more than 3,000 species, with a Japanese garden, bamboo groves, and a Giardino dei Semplici (over 300 species of medicinal plants). Noteworthy specimens include Cedrus deodara, Dasylirion glaucophyllum and Dasylirion acrotrichum, Erythrina crista-galli, and Liquidambar orientalis. There are several greenhouses containing a significant collection of cacti, as well as carnivorous plants, and tropical plants including euphorbia and orchids.
