Astronomical Museum with Planetarium

A 1st-century tomb surrounded by two farmhouses from the Middle Ages, one of which used to be a cheese store. Rather hidden behind a high wall, the tomb is rarely open to the public. You might be lucky on a Sunday: on the third Sunday of every month there is a guided tour at 11:00.

The most extensive collection of Etruscan art and artifacts anywhere. Fantastic collection and well worth the admission charge. A difficult museum to find, but a lovely display in a beautiful villa setting.

This church is roughly halfway between Piazza Navona and the Pantheon. It is most notable for a side chapel which contains three Caravaggio masterworks: "The Calling of St. Matthew", "St. Matthew and the Angel" and "Martyrdom of St. Matthew".

This church, which was commissioned by Ferdinand and Isabella of Spain, marks the point where, according to tradition, St. Peter was crucified. Particularly interesting for Irish visitors as it contains the graves of three Gaelic Chiefs who fled Ireland in 1607.

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).

This is a footbridge connecting Castel Sant'Angelo with the other side of the Tiber. It is a Roman bridge completed in 134 AD by Hadrian, to give access to his newly constructed mausoleum. Pilgrims used this bridge to reach St Peter's Basilica, hence it was earlier known as the "bridge of Saint Peter". In the seventh century, the castle and the bridge took on the name Sant'Angelo, when it is said that an angel appeared on the roof of the castle to announce the end of a plague. The statues of ten angels on the bridge reflect its name.

Also known as St Paul Outside the Walls. This is on the outskirts of Rome in an otherwise drab modern neighborhood. The enormous basilica is a faithful reconstruction, finished in 1854, of the ancient basilica which burned down in 1823. Parts of the original interior were rescued from the fire and have been extensively restored. Visiting in the afternoon may avoid the tourist coaches. Don't miss the medieval cloister, which survived the fire.

Home of the Abbot Primate of the Benedictine Confederation and Benedictine monks studying in Rome. Visit the monastic produce shop and listen to the best Gregorian chant in Rome during Vespers (19:15 each evening).

Permanent collection features paintings and drawings of Rome between the 18th and 20th centuries together with a fascinating black and white photo exhibition of Rome from 1950-80. Also offers rotating exhibitions, usually of the work of photographers.

They are posted at entrances to the Vatican City to provide security and protect the Pope. They wear very colourful clothing, similar to the uniforms worn by Renaissance-era soldiers. The Pontifical Swiss Guards is also the smallest and oldest standing army in the world, founded in 1506 by Pope Julius II. The origins of the Swiss guards, however, go back much further as the popes had regularly imported Swiss mercenaries during the 1400s.

Contains the ruins of several large villas that belonged to wealthy Roman families. You can buy a combined ticket for the Palatine Hill, the Roman Forum and the Colosseum here, avoiding the long lines at the Colosseum. While the Imperial and Roman Fora are probably more spectacular, overall, there are amazing sights on the Palatine Hill, so unless you are terribly short on time or find it too challenging to climb the hill, allow an hour or more for these sights, too.

A strange building, constructed by Reginald Pole, an English cardinal and later Archbishop of Canterbury, allegedly on the spot where he was able to escape from assassins sent by the English King Henry VIII.

On the site of the Roman baths, this museum houses an enormous collection of statues, etc.

Pope Sixtus IV della Rovere (1471-1481) gave order to replace the old Roman bridge by a new one. It was Pope Sixtus IV who also ordered the Sistine Chapel and the Opsedale di Santo Spirito to be built. So he ran out of money. He levied a tax on prostitution in order to gain money for the construction of the Ponte Sisto.

This archaeological site displays the thermal baths of the villa of the wealthy Herod Atticus. Also in the complex is a restored villa, until 2002 a private residence, that has an exterior completely covered with pieces from Roman ruins, including pipes used in the baths. There are some very helpful staff to show you around, although they only speak Italian. An interesting photographic exhibition in the house traces the development of the Appian Way over the last century. Almost opposite the entrance to the baths is a ruined tower known as the Torre di Capo di Bove.

Erected in 203. You can see it close up from Via della Curia also (without entering the Forum).

This is the largest square in Rome. It sometimes hosts pop concerts and is the focal point for Rome's New Year's Eve celebrations. The twin churches Santa Maria dei Miracoli (1681) and Santa Maria in Montesanto (1679) used to provide a clear welcome to Rome for those coming from the north. Much older, to the north of the piazza is yet another Santa Maria (see below). The Piazza del Popolo is considered as one of the most beautiful squares in Europe. It was enlarged and two streets, the Via di Ripetta and the Via del Babuino were added by order of Pope Sixtus V. In the middle of the square is an obelisk (see below). In 1809-1816, Giuseppe Valadier, Roman architect of French origin, gave the square its characteristic oval shape.

One of the oldest churches in the city. The nave is lined with a mismatched collection of columns taken from ancient Roman buildings. The apse is covered in gold mosaics from the 13th century, arguably the finest mosaics in the city. Impressive mosaics also on the front. According to legend the church was founded in 222, so it would be one of the most ancient churches in the city. Written records mention a church on this place in 337. What is visible today was built in the 12th century, by order of Pope Innocent III. The facade is decorated with mosaics representing the Virgin Mary and ten unidentified figures. Most probably these mosaics are the work of Petro Cavallini who created the mosaics of the lower apse dated 1290 representing scenes from the life of Mary. The mosaics of the upper apse in byzantine style are even older and date from 1140. The columns of the nave originate from the ancient Baths of Caracalla. The facade of Santa Maria in Trastevere is even more impressive at night when it is illuminated.

An underrated way to see fantastic art made after the Renaissance. Mainly Italian artists, notably De Chirico, but Cézanne, Degas, Kandinsky, Man Ray, Modigliani, Monet, Pollock and Van Gogh are also represented.
