Pyramid of Cestius

Perhaps the most fascinating building in Rome. The core of the structure began life as the mausoleum of Emperor Hadrian, built between 135 and 139 AD. Subsequent strongholds built on top of the mausoleum were in turn incorporated into a residence and castle by medieval Popes. The building was used as a prison until 1870 but now houses a museum. Opera buffs will be exhilarated to visit the balcony from which Tosca leaps to her death. Film buffs will recognise it as a setting from Angels and Demons.

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.

This is the attractive park on the hillside directly west of the Colosseum. Visible ruins in the area come from the Baths of Trajan. These baths were built on the top of the ruins of Domus Aurea - the Golden House of Nero (the Colosseum was built on the drained site of Nero's lake). The area underneath the park contains an enormous area from Nero's villa. It was restored at great expense in the 1980s and 1990s, opened to the public, and then closed again after a few years when it began to leak!

One of the most splendid (still private) Baroque grand palaces in Rome.

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.

This building was erected in the 16th century for Cardinal Girolamo Capodiferro. One century later it was acquired by another powerful Cardinal, Bernardino Spada, and was restored by Borromini, who created the forced perspective optical illusion in the arcaded courtyard.

A pleasant fountain in an out-of-the-way square. It was originally meant to have four dolphins rather than turtles, but the dolphins proved to be too large for the water pressure, so the turtles were added as an afterthought.

This remarkable building, designed partly by Bernini, houses the National Gallery of Ancient Art, and includes some famous paintings by Filippo Lippi and Caravaggio, as well as Raphael's "La Fornarina".

Inaugurated in 217 AD and used until the 6th Century. The baths were big enough for 1600 bathers at a time. Impressive and well-preserved. Used for operas in summer months (see Opera di Roma for details) and was the location for the famous "three tenors" concert in July 1990, at the time of the World Cup (soccer).

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.

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.

The 4th rebuilding of the meeting place for the Roman Senate, once converted into a church during the Middle Ages, but now restored since the 1930s.

Wandering around the shopping and residential district of Prati, close to the Vatican, you may notice rather a lot of lawyers' nameplates outside buildings. This is also Rome's legal district because of the proximity of the Palazzo di Giustizia or Palace of Justice. This massive monstrosity on the banks of the Tiber was built on alluvial soil, which necessitated a concrete platform to support the foundations. Despite this, later settlement of the building led to the need for restoration work in 1970 and it is said to be still sinking. There were many allegations of corruption during its construction, something not unknown in the Rome of today, and this, combined with its appearance, gave rise to its nickname of the Palazzaccio or Ugly Palace.

The villa was erected by order of Cardinal Ricci di Montepulciano in 1544. It was acquired by Cardinal Fernando di Medici in 1576. Since 1803 it is the French Academy in Rome. The academy was created in 1666 by the French King Louis XIV in order to enable painters to study in Rome. Nicolas Poussin was one of the first students, Ingres was director, and Fragonard and Boucher were students of the French Academy, but also musicians like Berlioz and Debussy studied here. Today the villa hosts occasional concerts and exhibitions. Its gardens can be visited.

The western end of the ancient Via Appia road connecting Rome to Brindisi in the heel of Italy, and as such the third world heritage site in Rome together with the Old Center and the Vatican. As such it's an important historical location, even if the remains of the gate aren't as impressive as the city's major sites. As Via Appia heads southeast out of Rome, and after a few kilometers the route is officially named Via Appia Antica and starts looking more historical: it gets narrow as a city street, the asphalt is replaced by a rock surface and the road is lined with parks and park-like areas and walled old buildings. This section has been described as the world's longest museum.

Ara Pacis is an altar to peace commissioned by the Roman Senate on 4 July 13 BC to honor the triumphal return from Hispania and Gaul of Augustus. It is universally recognised as a masterpiece. Following discovery of this work under a building in Rome, Mussolini built a protective building for it near the Mausoleum of Augustus, where it was reconstructed. A new building on the same site as Mussolini's was opened in 2006 and has been controversial. The mayor at the time said he would tear down the new structure. The basement of the new building features occasional exhibitions. You can see much of it from outside the building. Paying to go inside adds some background info, but not much more.

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.

An ethnographic collection of around 60,000 pieces from European indigenous cultures. Documents evolution from the Palaeolithic age to the Iron Age.

It was immortalised in 1960 by the Federico Fellini film La Dolce Vita. It is also the location of the US Embassy, in the massive Palazzo Margherita. Via Veneto went into a period of decline in the 1980s but has returned to popularity and the roadside cafes are the place to be seen if you are into that sort of thing.
