Flaminio Obelisk

With its strange Liberty- style buildings with influence from the Art Nouveau of the 1920s this small bunch of blocks is one of the most interesting, and less known, landmarks of the city. A must see.

If it is sunny, you'll catch a few young people and older gentlemen sitting at the base of a statue in the middle of the open space. The statue is a brooding, hooded Giordano Bruno—an excommunicated Dominican monk and one of the earliest cosmologists who held the idea of an infinite universe. He was burnt at the stake for heresy on this spot on 17 February 1600. The piazza is used as a marketplace during the day, and party central for college students and tourists at night. When the sky gets dark and the street lamps go on, the Campo de' Fiori fills with people and lovers wander arm in arm in the crowd. Over the buzzing of conversation and the occasional burst of laughter you may hear a young vocalist belt out O Sole Mio at the top of his lungs as change plunks into his accordion case.

Finished in 29 BC, marks the spot of Caesar's spontaneous cremation and Mark Antony's funeral speech, made famous by Shakespeare in his play Julius Caesar ("Friends, Romans, Countrymen, lend me your ears ...").

A very ancient church named after a saint who was in 1969 removed from the Roman Catholic calendar of saints for the lack of details of her life. But the church retains the name and is well worth visiting for an excellent 4th-century mosaic and attractive decorations on the facade. Visiting hours are short, but if you arrive close to 11:30, try talking to the attendant if you see him, and he might let you visit for a few minutes. The church is small, so 15 minutes should be long enough to see and absorb everything.

A truly quiet oasis close to the hustle and bustle of EUR. There are three churches in this complex and the doors are open all day, unlike city churches. The monks produce a range of products such as liqueurs, chocolate and honey, as well as a cure for the illnesses Romans suffer when the Scirocco wind blows in from the Sahara. These are on sale at a shop at the Abbey.

The Servian Wall was the first wall around Rome, built around the 3rd century BC. This well-preserved section provides a good opportunity to observe the construction methods of that time, particularly the use of tufa rock blocks

This is not the real name of the church on the corner by the main entrance to San Callisto but it is universally known by this name. By legend it is located on the spot where Saint Peter had a vision of the risen Christ while fleeing persecution in Rome. According to the tradition, Peter asked Jesus, Domine, quo vadis? “Lord, where are you going?” The current church is from 1637. Inside is a copy of a stone said to contain the imprints of the feet of Jesus; the original is maintained in San Sebastiano, further along the Appian Way

This little church is hard to find but well worth the extra effort although it is often closed when you get there. One of Borromini's masterpieces. It is located only a block from Piazza Navona, but not usually visible from the street, as you must enter the courtyard of an old palazzo to reach the church. Sant'Ivo is a small church the dome of which is shaped like the Star of David, but with every other point rounded. The steeple seen from the outside looks like it has a staircase wrapped around it that ascends to heaven. As the church was commissioned by the Barberini family that produced a number of popes and whose family symbol was the bee—some say the steeple resembles the stinger of the insect.

Inaugurated in 217 AD and used until the 6th Century. The baths were big enough for 1600 bathers at a time. Impressive and well-preserved. Used for operas in summer months (see Opera di Roma for details) and was the location for the famous "three tenors" concert in July 1990, at the time of the World Cup (soccer).

Unusual ancient Roman theatre with apartments built on top.

Unusual and fascinating round church dedicated to St. Stephen. It is the national church of Hungary in Rome. Dating from the 5th Century this is believed to be the largest round church in the world. Charles Dickens described its wall paintings of martyrdom and butchery as "hideous". A good starting point to visit the attractions of the Celio Hill (see Rome/Aventino-Testaccio).

A medieval church dating from the 6th century and home to the Bocca della Verità (Mouth of Truth). The Bocca della Verità at the entrance to the church is thought to be a 1st-century manhole cover. It is believed that if you put your hand in the mouth and tell a lie, the hand will be bitten off. Queues for the privilege of risking this can get rather long. Don't ignore the church, which is a gem, and has a separate entrance. Its mosaic floor in the Cosmatesque style is more rustic and less intricate than some others (Santa Maria in Trastevere, for example), but its simplicity gives it a solidity not found in the more ornate styles. S.M. in Cosmedin has a fine medieval choir enclosure and the tallest medieval belfry in Rome.

The two museums are on opposite sides of the Piazza del Campidoglio, It is recommended to book tickets online Built in the 17th century to a design based on an architectural sketch by Michelangelo. Highlights include the ancient Colossus of Constantine statue (the Colosseum was probably named for another giant statue, the Colossus of Nero which stood near the Flavian Amphitheatre as the Colosseum was originally known), The Dying Gaul, a magnificent marble sculpture that copies a bronze Greek original of the 3rd century BC and the Capitoline Venus. It also contains the remarkable original gilt bronze equestrian statue of emperor Marcus Aurelius (the one in the piazza is a replica).

The enormous building at the southeast end of the Circus Maximus is the headquarters of the UN Food and Agriculture Organization (FAO). From its roof are undoubtedly the best views of Rome, but you will need to know someone who works there to get past the strict security.

The remains of the ancient Roman archives, where Cicero and Seneca did research. Visible from the Forum and accessible through the Capitoline Museum.
