Port of Ripa Grande and Papal Arsenal

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.

Villa del Priorato di Malta or Magistral Villa, located on the Aventine Hill in Rome, is one of the two institutional seats of the government of the Sovereign Military Order of Malta. Along with Magistral Palace, the estate is granted extraterritorial status by Italy. It also hosts the Grand Priory of Rome and the embassy of the Sovereign Order of Malta to Italy.

The Church of St. Mary of the Priory (Italian: Chiesa di Santa Maria del Priorato), also known as St. Mary on the Aventine (Italian: Santa Maria in Aventino), is the monastery church of the Priory of the Knights of Malta on the Aventine Hill in Rome, and is dedicated to the Blessed Virgin Mary. The first church on this site was built in 939, when Odo of Cluny was given the Roman palace of Alberic II of Spoleto, which was then converted into a Cluniac Benedictine monastery. When the monastery was dissolved in the 14th-century, the site was acquired by the Knights of Malta, who had the church rebuilt in the 1550s. In 1760, the papal nephew and Grand Prior of the Knights, Cardinal Giovanni Battista Rezzonico, sought to improve the appearance of the buildings. On a limited budget, the church was substantially renovated between 1764-66 according to the designs of Giovanni Battista Piranesi. It is his only architectural work. According to a 2019 account, he "consolidated the structure of the 16th-century church and raised the side walls...restored the vault and designed the decoration for its new aspect". Piranesi also designed the piazza in front of the church, the Piazza dei Cavaliere di Malta. The fairly low wall around the piazza is articulated by panels with paired obelisks with stelae positioned between them. The church facade has paired fluted pilasters towards its edges to infer a temple front. The vertical linearity of the fluted pilasters act as a foil to enhance the more decorative reliefs of the facade. The reliefs on this facade, the entrance gate and the panels and stellae in the piazza include emblems and other references to the military and naval associations of the Knights of Malta and the Rezzonico family heraldry. The way in which they are represented indicates Piranesi's fascination with Rome's ancient past as they allude to motifs from Ancient Rome and Etruria.Piranesi's decoration of the church interior culminates in the very sculptural main altar. The church contains Piranesi's tomb and that of Bartolomeo Carafa (died 1405) designed by Paolo Romano. The Grand Priory of Rome (a division Knights of Malta) with support from the Fondazione Roma finances the restoration of both the interior and exterior that lasted from 2015 to 2019.

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.

As an ecclesiastical residential college in the Roman College tradition, it serves as both a house of formation for Benedictines, but also as a residence for over one hundred monks from around forty countries, religious, diocesan priests, and lay people.

The Basilica of Saint Sabina (Latin: Basilica Sanctae Sabinae, Italian: Basilica di Santa Sabina all'Aventino) is a historic church on the Aventine Hill in Rome, Italy. It is a titular minor basilica and mother church of the Roman Catholic Order of Preachers, better known as the Dominicans. Santa Sabina is the oldest extant ecclesiastical basilica in Rome that preserves its original colonnaded rectangular plan with apse and architectural style. Its decorations have been restored to their original restrained design. Other basilicas, such as Santa Maria Maggiore, have been ornately decorated in later centuries. Because of its simplicity, the Santa Sabina represents the adaptation of the architecture of the roofed Roman forum or basilica to the basilica churches of Christendom. It is especially famous for its 5th-century carved wood doors, with a cycle of Christian scenes, that is one of the earliest to survive. Santa Sabina is perched high above the Tiber to the north and the Circus Maximus to the east. It is next to the small public park of Giardino degli Aranci ("Garden of Oranges"), which has a scenic terrace overlooking Rome. It is a short distance from the headquarters of the Knights of Malta. Its cardinal priest is Jozef Tomko. It is the stational church for Ash Wednesday.
