Casal Rotondo stands as the largest mausoleum along the Appian Way, marking the sixth mile of this ancient Roman road. Over time, the structure has been adapted and now houses a small private villa that was once a farmhouse. Despite its size and prominence, the original person or family for whom the mausoleum was built remains a mystery.
Near Casal Rotondo, visitors will notice a distinctive wall assembled from ancient fragments. This wall was constructed by Luigi Canina, a notable 19th-century architect and archaeologist. Some of the ruins set into the wall refer to the Cotta family, but more recent research indicates that this family is not connected to Casal Rotondo itself.

The Piazza di Spagna (Spanish Square) is the most famous square in Rome. For a very long time it was the meeting point of all foreigners coming to Rome. In the 17th century it was the residence of the Spanish Ambassador to the Holy See. The area around the residence was Spanish territory and foreigners who stayed here without permission were forced to serve in the Spanish army. The Fontana della Barcaccia (Old Boat Fountain) on Piazza di Spagna was designed and built in 1627-29 by Pietro Bernini, father of the more famous Gian Lorenzo Bernini. The fountain celebrates the fact that before high walls were built along the banks of the Tiber Rome often used to flood. Once the waters were so high that a boat ended up in the square. The decorations on the fountain imitate the coat of arms of Pope Urban VII, Barberini'p, who ordered the fountain to be built. A less aesthetic occupant of the square is Italy's first McDonalds, dating back to 1986. Also in the piazza is a column erected in 1856 to commemorate the Immaculate Conception. The column is topped by a statue of the Virgin Mary, and rests on a base with statues of Moses, David, Isaiah and Ezekiel. The Pope visits the Piazza every year on December 8th to celebrate Immaculate Conception.
Contains the ruins of several large villas that belonged to wealthy Roman families. You can buy a combined ticket for the Palatine Hill, the Roman Forum and the Colosseum here, avoiding the long lines at the Colosseum. While the Imperial and Roman Fora are probably more spectacular, overall, there are amazing sights on the Palatine Hill, so unless you are terribly short on time or find it too challenging to climb the hill, allow an hour or more for these sights, too.
Built in the 9th century, this ancient basilica crowns the top of the Esquiline Hill. Tons of gold decorate the interior together with impressive mosaics (particularly when the floodlights are turned on), and there is a museum on the premises. If you are in Rome on Corpus Christi (Corpus Domini), which is the Thursday after the 8th Sunday after Easter, an early-evening service is held in San Giovanni by the Pope followed by a procession along Via Merulana to Santa Maria. Good opportunity for a close up view of the Pope. This is a very large church with lots to see, as for example, the main part of the church has two layers of mosaics and paintings high on the walls, the altar and apse are spectacular, and then there are several more or less large chapels you won't want to miss, including the one with the amazing golden baptismal font. Allow at least an hour if not an hour and a half or more to visit the interior, even if you do not take any special tours, and also allow time to view the exterior from all sides. Overall, at least 2 hours would not be too much time to allot.
Located a short walk west of the Colosseum, this well-preserved monumental arch was erected (soon after 315) to commemorate the victory of Constantine, the first Christian emperor, over his rival Maxentius at the Battle of the Milvian Bridge in 312. In general design, the Arch of Constantine imitates the century-earlier Arch of Septimius Severus (nearby in the Forum). The three arches are decorated utilizing mainly materials plundered from other imperial monuments by Trajan, Hadrian and Marcus Aurelius. The quality of its sculptural decoration, however, betrays the slow degradation that Classical Roman sculpture had experienced in the 3rd century AD.
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.
Contains the tomb of Pope Hadrian IV, the last non-Italian pope before Pope John Paul I.
Built after 1631, the crypt of the church contains a macabre display - a series of chapels decorated with the bones of 3700 dead friars. The bones are glued to the walls and ceilings in bizarre and striking decorations.
An underrated way to see fantastic art made after the Renaissance. Mainly Italian artists, notably De Chirico, but Cézanne, Degas, Kandinsky, Man Ray, Modigliani, Monet, Pollock and Van Gogh are also represented.
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.
Brand new museum designed to celebrate the art and architecture of the 21st century.
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!
Ballroom-like church which crowns part of the Capitoline Hill. Don't be fooled by the plain stone exterior.
A lovely, if somewhat run-down park (parts of it are blocked due to the poor state of the roads) with statues and a great view on the city.
Known properly as the Flavian Amphitheatre, this most famous of Roman landmarks takes its name from the giant statue of the emperor Nero that once stood near this location. The amphitheatre was capable of seating 50,000 spectators for animal fights and gladiatorial combats. It was a project started by the Emperor Vespasian in 72 and completed by his son Domitian sometime in the 80s. The Colosseum when completed measured 48 m high, 188 m in length, and 156 m in width. The wooden arena floor was 86 m by 54 m, and covered by sand.;Expect a long queue and an even longer wait. You can skip the queue if you decide to take a tour, but if you don't want a tour, you can STILL skip the queue. If you walk to the entrance for the Roman Forum, you can buy tickets there which allow you to bypass the queues. You can also buy tickets online. There are lots of people offering tours in English just outside the entrance to the Colosseum. Inside you can take a tour (English, Spanish, or German) every 30 minutes or so for an additional fee. The tours are given by knowledgeable archeologists, but they don't take you to any areas you couldn't visit on your own.
A truly quiet oasis close to the hustle and bustle of EUR. There are three churches in this complex and the doors are open all day, unlike city churches. The monks produce a range of products such as liqueurs, chocolate and honey, as well as a cure for the illnesses Romans suffer when the Scirocco wind blows in from the Sahara. These are on sale at a shop at the Abbey.
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.
