St. Peter's has many historical associations, with the Early Christian Church, the Protestant Reformation and so on, and with numerous artists, especially Michelangelo. As a work of architecture, it is regarded as the greatest building of its age. Vatican City is accessible by metro at Ottaviano Station.

It is a large plaza located directly in front of St. Peter's Basilica. At the centre of the square is an ancient Egyptian obelisk, erected at the current site in 1586. The square includes massive Tuscan colonnades, four columns deep, which embrace visitors in "the maternal arms of Mother Church".

The piazza is built on the site of the Stadium of Domitian, built in 1st century AD, and follows the form of the open space of the stadium. Defined as a public space in the last years of 15th century, Piazza Navona was transformed into a highly significant example of Baroque Roman architecture and art.

It is one of the best-preserved of all Ancient Roman buildings. It became a standard exemplar when classical styles were revived, and has been copied many times by modern architects.

It is a large complex of ruins thought to be the world's oldest shopping mall. The surviving buildings and structures, built as an integral part of Trajan's Forum and nestled against the excavated flank of the Quirinal Hill, present a living model of life in the Roman capital and a glimpse at the restoration in the city, which reveals new treasures and insights about Ancient Roman architecture.

It is a rectangular forum (plaza) surrounded by the ruins of several important ancient government buildings at the center of the city. It was for centuries the center of Roman public life: the site of triumphal processions and elections; the venue for public speeches, criminal trials, and gladiatorial matches; and the nucleus of commercial affairs. Many of the Roman kingdom's oldest and most important shrines and temples located on the Forum include the ancient former royal residence, the Regia (8th century BC), and the Temple of Vesta (7th century BC), as well as the surrounding complex of the Vestal Virgins.

They are a set of 135 steps climbing a steep slope, dominated by the Trinità dei Monti church at the top. It has been featured in popular media such as the 1953 film Roman Holiday. During Springtime, just before the anniversary of the foundation of Rome, part of the steps are covered by pots of azaleas.

Completed in 1762, it is the largest Baroque fountain in the city and one of the most famous fountains in the world. The fountain has appeared in several notable films, including Federico Fellini's La Dolce Vita. In the centre a robustly-modelled triumphal arch is superimposed on the palazzo façade. The centre niche or exedra framing Oceanus has free-standing columns for maximal light and shade.

The monument features stairways, Corinthian columns, fountains, an equestrian sculpture of Victor Emmanuel and two statues of the goddess Victoria riding on quadrigas.

The Capitoline Hill, one of the Seven Hills of Rome, was earlier known as Mons Saturnius, dedicated to the god Saturn. It contains few ancient ground-level ruins, as they are almost entirely covered up by Medieval and Renaissance palaces (now housing the Capitoline Museums) that surround a piazza, a significant urban plan designed by Michelangelo. There are several important temples built on Capitoline hill: the temple of Juno Moneta, the temple of Virtus, and the Temple of Jupiter Optimus Maximus Capitolinus.

Capitoline Museums are a single museum containing a group of art and archeological museums on top of the Capitoline Hill. The history of the museums can be traced to 1471, and since then, the museums' collection has grown to include a large number of ancient Roman statues, inscriptions, and other artifacts; a collection of medieval and Renaissance art; and collections of jewels, coins, and other items.
