San Callisto

The Palazzo San Callisto (also known as the Palace of Saint Callixtus) is a Baroque palace in the Trastevere neighborhood of Rome and one of the extraterritorial Properties of the Holy See. The original Palazzo is located in the Piazza di Santa Maria in Trastevere, the later extensions have their entrance in Piazza di San Callisto. The entire complex is one of the areas of the Holy See regulated by the 1929 Lateran Treaty signed with the Kingdom of Italy. As such it has extraterritorial status. In the courtyard of the palace is the well where, according to tradition, Pope Callixtus I was martyred in the year 222.

The Fountain in Piazza Santa Maria in Trastevere is a fountain located in the square in front of the church of Santa Maria in Trastevere, Rome, Italy. It is believed to be the oldest fountain in Rome, dating back, according to some sources, to the 8th century. The present fountain is the work of Donato Bramante, with later additions by Gian Lorenzo Bernini and Carlo Fontana.

The Basilica of Santa Maria in Trastevere (Italian: Basilica di Santa Maria in Trastevere); English: Our Lady in Trastevere) is a titular minor basilica in the Trastevere district of Rome, and one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140–43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I. The church has large areas of important mosaics from the late 13th century by Pietro Cavallini.

The Museo di Roma in Trastevere was established in 1977 in the restored Carmelite convent of Sant'Egidio. It was initially known as the Museo del Folklore e dei Poeti Romaneschi ("museum of folklore and Roman dialect poets"). Following a period of closure it was reopened under its present name in 2000. In addition to a permanent collection related to the recent culture of Rome the museum also houses temporary exhibitions, including the annual World Press Photo exhibition. It is part of the Museo di Roma.

Sant'Egidio is a convent church in Trastevere, Rome. Sant'Egidio (St. Giles) is the patron saint of hermits. The church was founded in 1630 and was abandoned by the nuns in 1971. In 1973, it was occupied by the Community of Sant'Egidio, which had been founded in 1968, and was still looking for a meeting place of its own. The community, which had not had a name before, then chose to name itself after its church. Together with the adjacent former Carmelite monastery, the church forms the seat of the Community of Sant'Egidio. It has been the titular church of Cardinal Matteo Zuppi since 5 October 2019.

Cencio la Parolaccia (Cencio's Profanities) is a restaurant in the Trastevere rione of Rome. It is mostly famous for the behaviour of its waiters, who curse at or otherwise verbally abuse the diners, including tourists. The restaurant mainly serves Roman cuisine.

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.

The Hospital of Santa Maria and San Gallicano, more commonly known as San Gallicano, is a building constructed in Rome between the end of 1724 and 1726 on the occasion of the Jubilee Year of 1725.

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.

The Fontana or Fontanone di Ponte Sisto, once known as the Fontanone dei Cento Preti, is an early 17th-century, monumental fountain now located in Piazza Trilussa, facing the south end of the Ponte Sisto, in Trastevere, Rome, Italy. It was reconstructed here in the late 19th century, originally erected across the river, attached to the former building of the Collegio Ecclesiastico.
