According to the legendary passio, two brothers, John and Paul, who were officials at the imperial court, suffered martyrdom in 362 in their home on the Caelian hill, during the reign of emperor Flavius Claudius Julianus. This basilica dedicated to these two Roman officers was erected starting from 398 and was used first as a domus ecclesiae by the Christian community.
The Basilica of Saints John and Paul on the Caelian Hill is an ancient basilica church in Rome, located on the Caelian Hill. It was originally built in 398.

Arco di Costantino
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.
Unusual and fascinating round church dedicated to St. Stephen. It is the national church of Hungary in Rome. Dating from the 5th century this is believed to be the largest round church in the world. Charles Dickens described its wall paintings of martyrdom and butchery as "hideous". A good starting point to visit the attractions of the Celio Hill (see Rome/Aventino-Testaccio).
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.
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 81 AD by the emperor Domitianus in dedication to his brother Titus, who died earlier that year and reigned as emperor from 79-81, overseeing the opening of the Colosseum in 80 and the eruption of Mt Vesuvius the previous year.
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.
