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.
The Porta Capena was a gate in the Servian Wall in Rome, Italy. The gate was located in the area of Piazza di Porta Capena, where the Caelian, Palatine and Aventine hills meet. Probably its exact position was between the entrance of Via di Valle delle Camene and the beginning of Via delle Terme di Caracalla, facing the curved side of the Circus Maximus.

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.
Case Romane del Celio
Early Roman houses dating back to the 1st century, believed to be homes of early Christians. Well-preserved frescoes and a small museum.
Celian Hill
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.
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).
The contours of the ancient stadium, built in the 6th century BC, are still visible in what is now a park in the shadow of the Palatine. Circus Maximus was primarily devoted to chariot races and was used for this purpose until around 550 AD. The stadium could seat up to 150,000 people. The original structure was built of wood. It burned down twice, on the second occasion starting the great fire when the Emperor Nero was said to have fiddled while Rome burned. It was in one of the tunnels here that Caligula met his end. Excavations began in 2009 at the east end of the circus and are likely to go on for some years.
A relaxing place to sit and recover from the exertions of sightseeing. Permanent collection plus annual competition.
