Rioni of Rome in the context of "Campus Martius"

The Hospital of the Holy Spirit (Italian: L'Ospedale di Santo Spirito in Sassia) is the oldest hospital in Europe, located in Rome, Italy. It now serves as a convention center. The complex lies in rione Borgo, east of Vatican City and next to the modern Ospedale di Santo Spirito (which continues its tradition). The hospital was established on the site of the former Schola Saxonum, a part of the complex houses the Museo Storico.

Borgo (sometimes called also I Borghi) is the 14th rione (administrative district) of Rome, Italy. It is identified by the initials R. XIV and is included within Municipio I.

Its coat of arms shows a lion (after the name "Leonine City", which was also given to the district), lying in front of three mounts and a star. These – together with a lion rampant – are also part of the coat of arms of Pope Sixtus V, who annexed Borgo as the 14th rione of Rome.

The Church of the Gesù (Italian: Chiesa del Gesù, pronounced [ˈkjɛːza del dʒeˈzu]), officially named Chiesa del Santissimo Nome di Gesù (English: Church of the Most Holy Name of Jesus), is a church located at Piazza del Gesù in the Pigna rione of Rome, Italy. It is the mother church of the Society of Jesus (best known as Jesuits). With its façade, described as "the first truly baroque façade", the church served as a model for innumerable Jesuit churches all over the world, especially in Central Europe and in Portuguese colonies. Its paintings in the nave, crossing, and side chapels became models for art in Jesuit churches throughout Italy and Europe, as well as those of other orders. The Church of the Gesù is one of the great 17th-century preaching churches built by Counter-Reformation orders like the Jesuits in the Centro Storico of Rome – the others being Sant'Ignazio, also of the Jesuits, San Carlo ai Catinari of the Barnabites, Sant'Andrea della Valle of the Theatines, and the Chiesa Nuova of the Oratorians.

First conceived in 1551 by Saint Ignatius of Loyola, the Spanish founder of the Society of Jesus active during the Protestant Reformation and the subsequent Catholic Counter-Reformation, the Gesù was also the home of the Superior General of the Society of Jesus until the wide suppression of the order in 1773. The church having been subsequently regained by the Jesuits, the adjacent palazzo is now a residence for Jesuit scholars from around the world studying at the Gregorian University in preparation for ordination to the priesthood.

Campo Marzio (Italian: [ˈkampo ˈmartsjo]) is the 4th rione of Rome, Italy, identified by the initials R. IV. It belongs to the Municipio I and covers a smaller section of the area of the ancient Campus Martius. The logo of this rione is a silver crescent on a blue background.

Santa Maria Maggiore (Italian pronunciation: [ˈsanta maˈriːa madˈdʒoːre]), also known as the Basilica of Saint Mary Major or the Basilica of Saint Mary the Great, is one of the four major papal basilicas and one of the Seven Pilgrim Churches of Rome. The largest Marian church in Rome, it is regarded as the first Marian sanctuary in the Western world and the mother of all sanctuaries.

Santa Maria Maggiore is located in Esquilino, the 15th rione (administrative district) of Rome, on the Piazza dell'Esquilino. Pursuant to the Lateran Treaty of 1929 between the Holy See and Italy, the basilica is in Italy and not Vatican City. However, as a property of the Holy See, Italy is obliged to protect its ownership and to concede to it "the immunity granted by international law to the headquarters of the diplomatic agents of foreign states". The complex of buildings therefore has a status somewhat similar to an embassy.

The Basilica of San Giovanni dei Fiorentini ("Saint John of the Florentines") is a minor basilica and a titular church in the Ponte rione of Rome, Italy.

Dedicated to St. John the Baptist, the protector of Florence, the new church for the Florentine community in Rome was started in the 16th century and completed in the early 18th, and is the national church of Florence in Rome.

Via Cavour is a street in the Castro Pretorio and Monti rioni of Rome, named after Camillo Cavour. It is served by the Rome Metro stations Cavour and Termini. The facade of the original permanent Roma Termini railway station reached this street, though it is now 200 metres further back towards the Esquiline. It runs from the Piazza del Cinquecento north of Termini Station, near the Baths of Diocletian, south-westward past the basilicas of Santa Maria Maggiore and San Pietro in Vincoli, and concludes at the Roman Forum, a total distance of 1.3 kilometres (13⁄16 mi). The street houses a large number of hotels and restaurants.
