San Saba

The Servian Wall was the first wall around Rome, built around the 3rd Century BC. This well-preserved section gives a good opportunity to see the construction methods used at that time, involving the use of blocks of tufa rock.

Next door to the Pyramid, this fine gate in the Aurelian Wall is named after St. Paul as the Via Ostiense leads to the basilica of St. Paul's Outside the Walls (see Rome/South).

A tomb for the wealthy Gaius Cestius, who died in 12 BC. Admission to the monument only by guided tours on specific dates (2nd and 4th Saturday every month, and in combination with a ticket to the Museum of Via Ostiense also on the 1st and 3rd Saturday of every month).

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.

Behind the pyramid, entered by the Via Caio Cestio, is the Protestant Cemetery where the poet John Keats was buried in 1821 and Percy Bysshe Shelley's ashes were also buried after his drowning in 1822. Richard Dana, author of Two Years before the Mast was buried there in 1882, and the Beat Generation poet Gregory Corso was buried there in 2001.

Small collection of railway carriages and related stuff. Really just for those with special interest in the topic. Entrance through the station if the main entrance is closed.
