Pigorini National Museum of Prehistory and Ethnography

Parco Savello is the name of the grounds and orange grove next to the Santa Sabina church at the top of the Aventino and also where you have one of the best views of the city. Families gather here to sit under the dozens of orange trees. The "Giardino degli Aranci" is also a well known spot for lovers at night. The best views are arguably from Janiculum hill, just across the Tevere (Tiber) river. Immediately below you, the Tiber snakes its way through the city, and directly beyond it you can see the lively medieval quarter of Trastevere. Beyond that is the majestic dome of St. Peter's Basilica, with the historic centre of Rome visible to the right.

It was built in 27 BCE, by Augustus' right hand man Marcus Agrippa, and later remodeled by the Emperor Hadrian (AD 125-128). This ancient temple was built as a temple to all the gods of the Roman state but has served as a Christian church since the 7th century. It is the only building from the Graeco-Roman world which has remained substantially intact and in continuous use throughout to the present day, and as it is still a functioning church, silence is requested during your visit. The Pantheon is celebrated for its large dome. From inside you'll see traces of the former bronze ceiling, melted down during the reign of Pope Urban VIII to make weapons for the fortification of the Castel Sant' Angelo. The hole in the center of the ceiling, though, is an original feature designed for architectural reasons (the dome would collapse without it.) If it happens to be raining, you should definitely go to the Pantheon to see the rain pouring into the building through the hole in the ceiling. There are holes in the ground that drain the water. The spectacular doors are Romans, but not the original. The original bronze beams of the pronao were melted down by Pope Urban VIII and might have been used to create Bernini's Baldacchino, or canopy, in Saint Peter's. The dome is the largest masonry dome in the world, larger than that of Saint Peter. The building now appears to be built in a depression, but this was not the original appearance. The street level at the sides and rear has risen about 10 metres (33 ft) since its construction due to the accumulation of debris from 2,000 years of settlement. This has necessitated the maintenance of the deep trench that keeps the building from being buried. The Pantheon was free for many years, but fees began being charged in 2023.

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.

A great little cathedral to visit, lovingly looked after by Irish Dominicans. There is an excavated older church below the medieval church you enter and a Mithraeum (temple to Mithras, whose cult was very popular with Roman soldiers from the 1st to 4th century AD) below that. The only place in Rome to hear the underground river that flows beneath the city.

Designed by Bramante to mark the spot of St. Peter's martyrdom, this delightful miniature building is considered a masterpiece of Renaissance architecture. Open to the public.

More modern than most Roman churches: it was not started until 1873. This is Rome’s Episcopalian church. Some very interesting artwork, particularly the mosaics by Edward Burne-Jones of the Pre-Raphaelite school.

In the Middle Ages pilgrims on their way to St. Peter's had to pass through the Via dei Coronari in order to cross the Tiber at Ponte St. Angelo. The street got its name from the people who sold rosaries to the pilgrims. It follows the ancient Via Recta which led from what is today Piazza Colonna to the Tiber. In the 15th century Pope Sixtus IV initiated the construction of private buildings. Today, several houses dating back to the 15th and 16th century may be seen. House nr. 156/157 is said to have been the House of Fiametta, the mistress of Cesare Borgia.

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.

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 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

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.

Regular shows plus an excellent astronomical museum.

Houses the tomb of St Lawrence. This basilica dates back to the 3rd century, when the area was already well populated. Surrounding it is Rome's cemetery, the Cimitero del Verano. San Lorenzo was damaged by Allied bombs in 1943 and the facade has been rebuilt.

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).

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 church was built by the Emperor Constantine (272-337) as a mausoleum for his daughters Constantina and Helena. It was part of a much larger cemetery complex, parts of which can still be seen. The mausoleum was consecrated as a church and dedicated to Constantina when she became a saint in 1254. The building is circular with an inner arcade resting on pairs of granite columns. It retains some marvellous mosaics from the 4th Century.

Four fountains from the time of Pope Sixtus V when much of Rome was redeveloped. A reclining deity is the theme of each sculpture. This is a busy intersection and if you don't look twice you may miss these exquisite examples of Roman mythology.

Casal Rotondo is the biggest mausoleum on the Appian Way, at about the sixth mile. It now incorporates a small private villa, originally a farmhouse. It is not known for whom it was built. The wall of fragments next to it, constructed by Luigi Canina, has ruins referring to the Cotta family but this family is now believed to not be associated with the Casal Rotondo.

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.
