Villa Medici

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.

Brand new museum designed to celebrate the art and architecture of the 21st century.

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

Minor basilica in 17th-century baroque style with good art inside. In a smaller Italian city, this might be a prime attraction, but in Rome, with its abundance of great churches, this is merely a pleasant church of secondary interest to visit if you are in the area.

Contains the tomb of Pope Hadrian IV, the last non-Italian pope before Pope John Paul I.

A tomb for the wealthy Gaius Cestius, who died in 12 BC. Admission to the monument only by guided tours on specific dates (2nd and 4th Saturday every month, and in combination with a ticket to the Museum of Via Ostiense also on the 1st and 3rd Saturday of every month).

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 Celian Hill is one of the seven hills of Rome. You immediately see the church of San Gregorio Magno. On this site monks were trained before setting off as missionaries to England at the end of the 6th Century. Further up the hill is Santi Giovanni e Paolo. At this point it is difficult to believe you are in the middle of a major city. This church was built in 398 over the home of two Roman soldiers, John and Paul, who were martyred for their Christian beliefs in 362. Excavations show that there were several burials on the site, a risky business as burials were illegal at that time. After the church you come to the back entrance of the Villa Celimontana park (jazz festival nightly in late June-August). The modern buildings before you reach the park are owned by Silvio Berlusconi’s television company. By the main entrance of the park note the boat-like fountain known as the “Navicella”. As you exit the main entrance to the left is the church of S. Maria in Domnica, which has some interesting mosaics. Next to this church is the Porta Esquilina, one of the gates from the original Servian walls of Rome. It dates back to the 4th century BC.

According to an inscription Emperor Augustus dedicated the obelisk to the sun in the 11th year of his consulate (10BC), after he had annexed Egypt to Rome. The obelisk is 24 m high. It was erected in Heliopolis in Egypt and was dedicated to Pharao Sethos I (1313-1292 BC) and Pharoa Ramses II (1292-1275 BC). Augustus brought the obelisk to the Circus Maximus, where it was rediscovered in 1587, broken into three pieces and was relocated to Piazze del Popolo on the orders of Pope Sixtus V in 1589.

The first basilica was constructed in the 4th century and dedicated to San Sebastian, a martyr of the 3rd century. Sebastian's remains were transferred to St. Peter's in 826, prior to a Saracen assault when the church was destroyed. The current church was largely constructed in the 17th-century. Until the Great Jubilee in 2000 this was one of the Seven Pilgrim Churches of Rome, i.e. the churches that all Roman Catholic pilgrims were expected to visit. However, at that time it was replaced by the Sanctuary of Divino Amore (see below). Entrance to the catacombs, which are smaller than the others in the area, is to the right of the church entrance. The area where you buy tickets and wait for tours has a good display of sarcophagi from the catacombs. You can rent a bicycle at the catacombs for further exploration of the Appian Way.

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.

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.

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.

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.

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 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.

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.

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

The Collegio Romano was a college of the Jesuit order. Many popes, cardinals and bishops were educated here. Since 1870 it has been a secular (non-monastic) school. The coat of arms on the doorway is that of Pope Gregory XIII (1572–1585). The tower was erected in 1787 and served as an observatory. Until 1925 all clocks in Rome were set after that of the Collegio Romano.
