Pontifical Swiss Guard

This church was built next to the mausoleum of Santa Costanza in the 7th Century and is on top of catacombs. It is very unusual in that the floor level is at the level of the catacomb floor, and the street entrance is at the level of the second floor gallery. The body of St. Agnes lies in a silver sarcophagus. There are several stories about her death at the age of 13 in 304 AD. One is that the prefect Sempronius wanted her to marry his son, and condemned her to death when she refused. Roman law did not permit the execution of virgins, so he ordered her to be raped but her virginity was miraculously preserved. She was then condemned to be burnt at the stake but the wood would not burn. Another is that she was stripped naked by the Emperor Diocletian because of her refusal to marry but that her hair then grew rapidly to preserve her modesty.

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.

This remarkable building served as the site of the Apostolic Chancellery, or offices of the Pope, for centuries, and now houses a Vatican court. Tucked behind the facade is also the Basilica of San Lorenzo in Damaso, an ancient Roman house church rebuilt in the 15th century.

This church is literally right next to the Pantheon. It is one of Rome's only Gothic churches, and well worth looking inside, although its plain square façade makes it look inconspicuous from outside. Excellent stained glass windows.

On the other side of the Via dei Fori Imperiali to the Roman Forum. Well-preserved market area that doubled as a way of stopping the Quirinal Hill from collapsing. Below in the Forum is Trajan's Column, built in 113 with reliefs depicting the Emperor Trajan's vistories in battle.

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.

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.

Pope Nicholas III connected Castel Sant'Angelo to St. Peter's by a covered fortified corridor called the Passetto di Borgo. This proved useful for Pope Clement VII during the Sack of Rome (1527). You can still see much of the Passetto by walking along the Borgo Sant'Angelo, which runs parallel to, and north of, the Via della Conciliazione.

Fantastic Byzantine mosaics and some other interesting artwork. Not to be missed. 30 minutes are sufficient for a relaxed visit.

Porta San Sebastiano is a gate in the amazingly well-preserved Aurelian Walls. Inside and upstairs is a museum dedicated to the construction of the walls and their recent restoration. You can take a walk along the top of the walls. At the museum you can also arrange to visit the Tomb of the Scipios (Sepolcro degli Scipiani) and a nearby Roman Columbarium (tomb for cremated remains), the entrance for which is 200 m back towards Rome along the Via Di Porta San Sebastiano. No wheelchair access.

Completed in 179 BC.

This pleasant park contains very well-preserved ruins of two aqueducts and some of the original surface of the Roman Via Latina. Gets crowded on Sundays but almost empty the rest of the week during term time. Good place for joggers.

A magnificent patrician house with beautiful gardens. It was built by order of Cardinal Alessando Albani in 1743-1763 in order to accommodate his collection of art. The collection was taken care of by the Winkelmann, adviser and friend of the cardinal. In Rome, Winkelmann wrote his "Geschichte der Kunst des Altertumns (HIstory of the Art of Antiquity)", which made him the founder of classical archaeology. The painted ceiling of the great hall depicting Mount Parnassus is by the German painter Anton Raphael Mengs who was considered as the greatest painter in Rome in the 18th century. A permission to visit is to be requested by email or fax from Principi Torlonia's administration where you'd need to indicate date and time desired, your name and number of people in your party (max. 10).

A truly monumental stairway of 135 steps (similar to climbing eight flights of stairs), built with French funds between 1721 and 1725 in order to link the Bourbon Spanish embassy to the Holy See (still located in the piazza below), with the Bourbon French church (its monastery founded in 1495) above. Don't sit on them though, or eat, or push a baby stroller on them, or do anything else that might obstruct pedestrians, make them dirty, or cause additional wear and tear, or else you will have to pay a fine that ranges from €250 to €400.

By Borromini, reputed to be on the spot where St. Agnes was martyred in the 4th century AD. This lovely basilica church is small with an almost circular interior. It is undergoing rehabilitation and the facade and dome are hidden in scaffolding. It seems to be open only until noon.

The first pedestrian-only bridge was built here in 206 BC and marks the passage of the Roman Via Flaminia over the Tiber. In 115 BC, the original bridge was demolished and rebuilt. It has been restored and remodelled several times since. In 2006, the bridge began attracting couples who, influenced by a movie, used a lamppost on the bridge to hang padlocks as a sign of their love, locking the padlock to the lamppost, then throwing the key behind them into the river. In 2007 the lamppost collapsed under the weight! Feeling sorry for the lovers the mayor ordered construction of steel posts, where padlocks can once again be hung.

Where you can find the building of the House of Representatives.
