The Amphitheatrum Castrense is a Roman amphitheatre in Rome, next to the church of Santa Croce in Gerusalemme. Both the Amphiteatrum and the Circus Varianus were part of the palatial villa known as the Sessorium. The Regionary Catalogues name it as the "Amphitheatrum Castrense", which could mean it was an amphitheatre connected to an imperial residence, which was not uncommon.

The Basilica of the Holy Cross in Jerusalem or Basilica di Santa Croce in Gerusalemme, (Latin: Basilica Sanctae Crucis in Hierusalem) is a Catholic Minor basilica and titular church in rione Esquilino, Rome, Italy. It is one of the Seven Pilgrim Churches of Rome. According to Christian tradition, the basilica was consecrated circa 325 to house the relics of the Passion of Jesus Christ brought to Rome from the Holy Land by Empress Helena, mother of Roman Emperor Constantine I. The basilica's floor was covered with soil from Jerusalem, thus acquiring the title in Hierusalem; it is not dedicated to the Holy Cross of Jerusalem, but the basilica was considered in a sense to be "in Jerusalem" (much in the way that an embassy today is considered extraterritorial). The current Cardinal Priest of the Titulus S. Crucis in Hierusalem is Juan José Omella.

Aqua Anio Novus (Latin for "New Anio aqueduct") was an ancient Roman aqueduct. Like the Aqua Claudia, it was begun by emperor Caligula in 38 AD and completed in 52 AD by Claudius, who dedicated them both on August 1. Together with the Aqua Anio Vetus, Aqua Marcia and Aqua Claudia, it is regarded as one of the "four great aqueducts of Rome."

The tomb of Marcus Vergilius Eurysaces the baker is one of the largest and best-preserved freedman funerary monuments in Rome. Its sculpted frieze is a classic example of the "plebeian style" in Roman sculpture. Eurysaces built the tomb for himself and perhaps also his wife Atistia around the end of the Republic (ca. 50–20 BC). Located in a prominent position just outside today's Porta Maggiore, the tomb was transformed by its incorporation into the Aurelian Wall; a tower subsequently erected by Honorius covered the tomb, the remains of which were exposed upon its removal by Gregory XVI in 1838. What is particularly significant about this extravagant tomb is that it was built by a freedman, a former slave. Three sides of the slightly trapezoidal structure remain largely intact. All have the same form, with over a plain lower storey, now mostly below ground level but exposed, a storey consisting of pairs of engaged columns between flat slabs, all crammed together with no space in between. The effect is far from the classical orders; at the corners the slabs turn to pilasters rising at the top level to unorthodox capitals combining scrolls at the sides with plant forms in the centre. There are unusual circular openings in the topmost storey, now thought to represent kneading-basins or grain-measuring vessels. Below a cornice is the frieze, with continuous scenes in relief showing the operation of the bakery where Eurysaces made what was evidently a considerable fortune. Reconstructions imagine a gently rising roof above this, now lost.

The Porta Maggiore ("Larger Gate"), or Porta Prenestina, is one of the eastern gates in the ancient but well-preserved 3rd-century Aurelian Walls of Rome. Through the gate ran two ancient roads: the Via Praenestina and the Via Labicana. The Via Prenestina was the eastern road to the ancient town of Praeneste (modern Palestrina). The Via Labicana (now called the Via Casilina) heads southeast from the city.

The Porta Maggiore Basilica is an underground basilica discovered in 1917 near Porta Maggiore in Rome. It is dated to the first century BC. It is believed to have been the meeting place of the neo-Pythagoreans, and is the only historical site that has been associated with the neo-Pythagorean movement. This school of mystical Hellenistic philosophy preached asceticism and was based on the works of Pythagoras and Plato. It was a precursor to the basilicas built during the Christian period, centuries later. It was opened to small groups of visitors in April 2015.

The Aqua Appia was the first Roman aqueduct, constructed in 312 BC by the co-censors Gaius Plautius Venox and Appius Claudius Caecus, the same Roman censor who also built the important Via Appia.The Appia fed the city of Rome with an estimated 73,000 cubic metres (2,600,000 cu ft) of water per day.

Lodi is an underground station of Line C of the Rome Metro. It served as the western terminus of Line C since its opening, on June 29, 2015, until May 12, 2018, when the terminus moved to San Giovanni. The station is not exactly located in Piazza Lodi, after which it is named, but further west in Via La Spezia, between Via Orvieto and Piazza Camerino. Works started in 2007 and were finished in January 2015. The station opened on 29 June 2015.

Circus Varianus was a large Roman circus, started during the reign of Caracalla (r. 198-217) and located in the palatial villa complex known as the Horti Spei Veteris (later the Sessorium), which included the Amphitheatrum Castrense. This circus was where Elagabalus (r. 218-222) raced chariots under the family name of Varius, giving the site its name. The circus was later restructured by Elagabalus, who removed the western end to create more space for the palace by moving the starting gates (carcares) back and building two towers at the end.Remains of the circus survive to the south of Porta Maggiore, next to the Aurelian Walls, near the church of Santa Croce in Gerusalemme. The dimensions of the circus were 565 x 125 m, only slightly smaller than the Circus Maximus (600 x 150 m).In around 271 AD the circus was cut in two by the Aurelian Walls and the major part then lay outside the city walls so became unused.According to records in the 16th century, an obelisk was found at the site, measuring 9.25 meters tall. It had originally been located at the temple dedicated to Antinous at Antinoöpolis and was moved in the reign of Elagabalus. After being discovered, the obelisk was moved to the Palazzo Barberini in 1633, from there to the Vatican in 1769, and reached Monte Pincio in 1822 where it resides currently.

The Temple of Minerva Medica is a ruined nymphaeum of Imperial Rome which dates to the 4th century. It is located between the Via Labicana and Aurelian Walls and just inside the line of the Anio Vetus. Once part of the Horti Liciniani on the Esquiline Hill, it now faces the modern Via Giolitti. It was once thought to be the temple to Minerva Medica ("Minerva the Doctor") mentioned by Cicero and other sources. The decagonal structure in opus latericium is relatively well preserved, though the full dome collapsed in 1828. It is surrounded on three sides with other chambers added at a later date. There is no mention of it in ancient literature or inscriptions. The structure represents a transition in Roman secular architecture between the octagonal dining room of the Domus Aurea and the dome of the Pantheon, and the architecture of nearby Byzantine churches. The diameter of the hall was about 24 meters, and the height was 33 meters — important from the structural point of view, especially for the ribs in the dome. In the interior, there are nine niches besides the entrance; and above these are ten corresponding round-arched windows. Both the interior and exterior walls were once covered with marble.In Flavio Biondo's 15th-century Roma Instaurata, these ruins are called Le Galluzze, a name of uncertain meaning that had been applied earlier to some ruins near the basilica of Santa Croce in Gerusalemme. Its misidentification as the Republican-era temple dates to the 17th century, based on the incorrect impression that the Athena Giustiniani had been found there.

Villa Wolkonsky (in Italian, the word villa usually includes not only a large building but also its grounds) is the official residence of the British ambassador to Italy in Rome. The entrance to the villa is located at 4, Via Ludovico di Savoia.

Porta San Giovanni is a gate in the Aurelian Wall of Rome, Italy, named after the nearby Archbasilica of Saint John Lateran.
