Trinità dei Monti

More of an enormous traffic circle than a piazza, but a good central location. The centerpiece is the enormous Vittorio Emanuele Monument (aka the Wedding Cake or the Typewriter) with the Capitoline hill next door. Mussolini used to harangue Romans from the first floor balcony of Palazzo Venezia (see under Museums), to the west of the square.

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

Church built on the site of three Roman pagan temples, which can be explored underground for a small fee paid at a desk near the church entrance.

This church can be an interesting deviation if you are passing through its neighbourhood. It is believed to be the grave of the Saints Ciro and Giovanni, killed during the time of the Emperor Diocletian. The original name was Abba Cyrus and through Appaciro and then Appacero it finally became Pacera, very close to today's Passera. The building is on top of a 3rd century building still visible in the lower floor and in the underground. The main part of the building dates back to the 9th century as do the frescoes on the higher floor. Some of the frescoes have been restored. Downstairs there is a small quadrangular room and the underground, where the remains of the two Saints are supposed to be. There are still visible 3rd century traces of Roman frescoes; in front of the stair you can enjoy a small bird, the Justice, and an athlete while in the vault some eight apex stars.

Beautiful park, the 2nd largest in Rome (after Villa Doria Pamphili) at 450 acres/182 hectares. Hosts concerts on summer evenings. former summer residence of Italian monarchs. Also known for it's bunker.

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.

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.

Romans and leaders of Rome's defeated enemies were imprisoned here where they either died of starvation or strangulation. According to legend, St. Peter was also imprisoned here.

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.

Next door to the Pyramid, this fine gate in the Aurelian Wall is named after St. Paul as the Via Ostiense leads to the basilica of St. Paul's Outside the Walls (see Rome/South).

Perhaps most famous for a large model of imperial Rome, but also has a large display of various aspects of ancient Rome, using plaster casts, models and reconstructions of works found in museums throughout the world.
